0f673f5d7a Omit needless words: distinguish class vs. instance properties for pruning.
A class method named "bezierPath" should not prevent
"appendBezierPath" from being stripped.

106bf80152 Omit needless words: don't prune "properties" of the context from the base name.
The properties of a context indicate those things that are considered
"contained within" the context (among other things). This helps us
avoid producing overly-generic names when we identify a redundancy in
the base name. For example, NSView contains the following:

  var gestureRecognizers: [NSGestureRecognizer]
  func addGestureRecognizer(gestureRecognizer: NSGestureRecognizer)
  func removeGestureRecognizer(gestureRecognizer: NSGestureRecognizer)

Normally, omit-needless-words would prune the two method names down to
"add" and "remove", respectively, because they restate type
information. However, this pruning is not ideal, because a view isn't
primarily a collection of gesture recognizers.

Use the presence of the property "gestureRecognizers" to indicate that
we should not strip "gestureRecognizer" or "gestureRecognizers" from
the base names of methods within that class (or its subclasses).

Note that there is more work to do here to properly deal with API
evolution: a newly-added property shouldn't have any effect on
existing APIs. We should use availability information here, and only
consider properties introduced no later than the entity under
consideration.

44e34850ae Omit needless words: give initial Boolean parameters argument labels.
When the first parameter of a function has Boolean type, try to create
an argument label for it. We start with the (normally non-API)
parameter name as the argument label, then try to match that against
the end of the base name of the method to eliminate redundancy. Add a
little magic, and here are some diffs:

    -  func openUntitledDocumentAndDisplay(_: Bool) throws -> NSDocument
    +  func openUntitledDocument(display _: Bool) throws -> NSDocument

    -  func fontMenu(_: Bool) -> NSMenu?
    -  func fontPanel(_: Bool) -> NSFontPanel?
    +  func fontMenu(create _: Bool) -> NSMenu?
    +  func fontPanel(create _: Bool) -> NSFontPanel?

0addd80bb3 Transform EditorPlaceholderExpr into trap if executed in playground mode.
Allow untyped placeholder to take arbitrary type, but default to Void.
Add _undefined<T>() function, which is like fatalError() but has
arbitrary return type. In playground mode, merely warn about outstanding
placeholders instead of erroring out, and transform placeholders into
calls to _undefined(). This way, code with outstanding placeholders will
only crash when it attempts to evaluate such placeholders.

a899872d91 Reapply r31105, with some fixes to invalid unconstrained generics. These fixes correct
the regressions that r31105 introduced in the validation tests, as well as fixing a number
of other validation tests as well.

Introduce a new UnresolvedType to the type system, and have CSDiags start to use it
as a way to get more type information out of incorrect subexpressions.  UnresolvedType
generally just propagates around the type system like a type variable:
 - it magically conforms to all protocols
 - it CSGens as an unconstrained type variable.
 - it ASTPrints as _, just like a type variable.

The major difference is that UnresolvedType can be used outside the context of a
ConstraintSystem, which is useful for CSGen since it sets up several of them to 
diagnose subexpressions w.r.t. their types.

For now, our use of this is extremely limited: when a closureexpr has no contextual
type available and its parameters are invalid, we wipe them out with UnresolvedType
(instead of the previous nulltype dance) to get ambiguities later on.

We also introduce a new FreeTypeVariableBinding::UnresolvedType approach for
constraint solving (and use this only in one place in CSDiags so far, to resolve
the callee of a CallExpr) which solves a system and rewrites any leftover type 
variables as UnresolvedTypes.  This allows us to get more precise information out,
for example, diagnosing:

 func r22162441(lines: [String]) {
   lines.map { line in line.fooBar() }
 }

with: value of type 'String' has no member 'fooBar'
instead of: type of expression is ambiguous without more context

This improves a number of other diagnostics as well, but is just the infrastructural
stepping stone for greater things.

9fe51033a4 Allow lazy resolution of nested archetypes within the archetype builder.
While the archetype builder is constructing archetypes, it eagerly
produces the set of nested archetypes for each archetype. If the
construction of any of those nested archetypes refers to another
archetype, we would fail unceremonerously with an assertion. Fill in
the nested type names (but not their actual types) eagerly, allowing
the actual types to be determined lazily.

This is plumbing for rdar://problem/21620908, which still trips an
unrelated assertion, preventing a useful testcase at this step.

This prevents us from seeing a less useful error message from SILGen
further down the line.

Also fix a bug where @objc without importing Foundation was not diagnosed
after the first top-level form. Some tests were relying on this behavior,
so fix those tests, either by splitting off the objc parts of the test, or
just by passing the -disable-objc-attr-requires-foundation-module flag.

de81a3e15f Prefer using known-identifiers to using getIdentifier.
I didn't add anything to the table, just made use of what was already there.
We have plenty of additional calls to getIdentifier that could probably benefit
from this kind of easy access as well.

This commit also removes FOUNDATION_MODULE_NAME and OBJC_MODULE_NAME from
Strings.h. Neither of these is likely to change in the future, and both
already have KnownIdentifiers equivalents in use.

2d66428272 Clean up KnownIdentifiers.def.
- Remove unused names.
- Define IDENTIFIER in terms of IDENTIFIER_WITH_NAME.
- Adjust each name to always match the corresponding value in case.
- Add an IDENTIFIER_ macro for the common case of defining an underscored name.
- Avoid creating names with double underscores, which are technically reserved
  by the C++ standard.

There are two special cases I left in here for the identifiers '_code' and
'_domain'. I didn't want to call these simply 'Id_code' and 'Id_domain' for
fear someone would try to use them as 'code' and 'domain', so I made them into
'Id_code_' and 'Id_domain_' for now.

66e1f37e62 SILGen: Reabstraction for vtable entries.
When a derived class specializes its base class, e.g. 'class Derived: Base<Int>', the natural abstraction levels of its methods may differ from the original base class's more abstract methods. Handle this by using the reabstraction machinery to thunk values when necessary. Merge the existing optionality thunking support into the reabstraction code, where witness thunking and similar convention adjustments may also be able to use it, if we desire.

b8995b0aa3 Transform the Module class into ModuleDecl.
Modules occupy a weird space in the AST now: they can be treated like
types (Swift.Int), which is captured by ModuleType. They can be
treated like values for disambiguation (Swift.print), which is
captured by ModuleExpr. And we jump through hoops in various places to
store "either a module or a decl".

Start cleaning this up by transforming Module into ModuleDecl, a
TypeDecl that's implicitly created to describe a module. Subsequent
changes will start folding away the special cases (ModuleExpr ->
DeclRefExpr, name lookup results stop having a separate Module case,
etc.).

Note that the Module -> ModuleDecl typedef is there to limit the
changes needed. Much of this patch is actually dealing with the fact
that Module used to have Ctx and Name public members that now need to
be accessed via getASTContext() and getName(), respectively.

e7547adabd AST: Initial work to canonicalize generic signatures for mangling.
Currently GenericSignature::getCanonicalSignature isn't able to canonicalize the set of requirements due to fragile dependencies on generic signatures matching AllArchetypes order of their originating GenericParamLists. However, we shouldn't let that stop us from getting the mangling right, so implement a "getCanonicalManglingSignature" that builds the true canonical signature by feeding it into an ArchetypeBuilder and shedding unnecessary constraints. For now, just handle conformance and base class constraints; still to do are same-type constraints.

aa0e763940 Imbue ASTContext with a lazy resolver.
Have TypeChecker's constructor register itself as the lazy resolver,
and its destructor unregister itself. This introduces the
completely-sensible restriction that there can only be one type
checker active for an ASTContext at a time, which is the case already.

Use ASTContext's lazy resolver in a single place that's been causing
trouble (rdar://problem/20363958, rdar://problem/19773096), where
deserializing a protocol conformance can cause us to pass a null lazy
resolver into the protocol conformance table, which doesn't handle it
well. This commit fixes those issues, which I'm unable to reduce down
to a sane-enough test case to commit.

This commit implies a ton of cleanup work to eliminate LazyResolver
parameters from *everywhere*, deriving them from the ASTContext in the
few places they're needed as well. It's a good direction, but that
cleanup can be evolutionary.

9bd774fd57 Eliminate ExtensionDecl::(get|set|)Conformances.
Stop storing a conformances array on ExtensionDecls. Instead, always use the conformance lookup table to retrieve conformances (which is lazy and supports multi-file, among other benefits).

As part of this, space-optimize ExtensionDecl's handling of conformance loaders. When one registers a conformance loader, it goes into a DenseMap on ASTContext and gets erased once we've loaded that data, so we get two words worth of space back in each ExtensionDecl.

1511d7a15a Start building conformances when requested in the AST.
Previously, we would require the type checker to be able to build a
conformance, which meant we would actually have to lie in the AST
about having a conformance (or crash; we did the form). Now, we can
form the conformance in the AST and it will be checked in the type
checker when needed. The intent here is to push conformance creation
into the conformance lookup table.

To get here, we had to stop relying on the broken, awful,
ASTContext-wide conformance "cache". A proper cache can come back once
the model is sorted out.

59c22383fb Rework PatternBindingDecl to maintain a list of pattern/initexpr pairs inside of it.
Previously, a multi-pattern var/let decl like:
  var x = 4, y = 17

would produce two pattern binding decls (one for x=4 one for y=17).  This is convenient
in some ways, but is bad for source reproducibility from the ASTs (see, e.g. the improvements
in test/IDE/structure.swift and test/decl/inherit/initializer.swift).

The hardest part of this change was to get parseDeclVar to set up the AST in a way
compatible with our existing assumptions. I ended up with an approach that forms PBDs in 
more erroneous cases than before.  One downside of this is that we now produce a spurious
  "type annotation missing in pattern"
diagnostic in some cases.  I'll take care of that in a follow-on patch.
