Sema: Better support for nested generic functions
There was a weird corner case with nested generic functions that would fail in the SIL verifier with some nonsense about archetypes out of context. Fix this the "right" way, by re-working Sema function declaration validation to assign generic signatures in a more principled way. Previously, nested functions did not get an interface type unless they themselves had generic parameters. This was inconsistent with methods nested inside generic types, which did get an interface type even if they themselves did not have a generic parameter list. There's some spill-over in SILGen from this change. Mostly it makes things more consistent and fixes some corner cases. |

AST: When performing qualified lookup of a member type, filter out non-types earlier
With the previous resolveTypeInContext() patch, a few compiler
crashers regressed with this problem, presumably because we were now
performing lookups in more contexts than before.
This is a class of problems where we would attempt a recursive
validation:
1) Generic signature validation begins for type T
2) Name lookup in type context finds a non-type declaration D nested in T
3) Generic signature validation begins for D
4) The outer generic context of D is T, but T doesn't have a generic
signature yet
The right way to break such cycles is to implement the iterative
decl checker design. However when the recursion is via name lookup,
we can try to avoid the problem in the first place by not validating
non-type declarations if the client requested a type-only lookup.
Note that there is a small semantic change here, where programs that
were previously rejected as invalid because of name clashes are
now valid. It is arguable if we want to allow stuff like this or not:
class A {
func A(a: A) {}
}
or
class Case {}
enum Foo {
case Case(Case)
}
However at the very least, the new behavior is better because it
gives us an opportunity to add a diagnostic in the right place
later. The old diagnostics were not very good, for example the
second example just yields "use of undeclared type 'Case'".
In other examples, the undeclared type diagnostic would come up
multiple times, or we would generate a cryptic "type 'A' used within
its own definition".
As far as I understand, this should not change behavior of any existing
valid code.

Sema: Fixes for protocol typealiases
This is a big refactoring of resolveTypeInContext() which makes
the function clearer to understand by merging various special
cases and generalizing the logic for walking parent and superclass
contexts to cover more cases.
This improves typealiases in protocols a bit:
1) Previously a typealias in a protocol either had to be concrete,
or consist of a single path of member types from Self, eg
Self.A.B. Lift this restriction, so we can now write things like
protocol Fireworks {
associatedtype Exploding
typealias Exploder = Exploding -> [Exploding]
}
2) Protocol typealiases can now be accessed via qualified lookup
on concrete types. Getting this working for unqualified lookup
requires further refactorings which will be in a subsequent
patch.

Disable typealiases in protocols and add frontend flag to re-enable.
Goes back to Swift 2.2 behavior of treating the 'typealias' keyword inside a protocol as a deprecated form of an associatedtype. To get the newer (but still partly buggy) behavior of treating it as an actual typealias, add "-Xfrontend -enable-protocol-typealiases" to the compile invocation. 'decl/typealias/typealias.swift' now uses this flag to continue testing the enabled behavior. |

[Parse] Improve diagnostics in inheritance clauses
Before, a keyword in an inheritance clause would lead to a long list of errors not really showing what was wrong. A special case is added to handle protocol composition; in inheritance clauses the protocols don't have to be composed with 'protocol<>'. |

Sema: Generic classes and subclasses of generic classes now inherit required initializers
Initializers are inherited by synthesizing an implicit decl which
delegates to super.init(). Previously this was only done if the
class and superclass were concrete.
The only thing missing was that we weren't computing an interface
type for the synthesized constructor. There are two steps to this:
- First, we must map the contextual types of the superclass
initializer's ParamDecls to the subclass generic context.
- Second, we must set the interface type by calling the new
configureInterfaceType() method, extracted from from
validateGenericSignature().
Note that configureInterfaceType() now uses the new
AbstractFunctionDecl::hasThrows() flag to set the 'throws' bit on
the function type. Previously, validateGenericFuncSignature()
would look at getThrowsLoc().isValid(), which is not correct for
imported, implicitly-generated or de-serialized decls that 'throw',
because none of those have source location information.
We still don't allow inheriting initializers which have their
own generic parameter list, like 'init<T>(t: T) {...}'. That
requires a little bit more refactoring.
Progress on <rdar://problem/23376955>.

AST: Fix some nested generics issues exposed by generic initializer inheritance
BoundGenericType::getSubsitutions() would only look at the bound generic arguments of the innermost type, ignoring parent types. However, it would then proceed to walk the AllArchetypes list of all outer generic parameter lists when forming the final result. The gatherAllSubstitutions() would also walk through parent types. As a result, outer generic parameters would appear multiple times. Simplify gatherAllSubstitutions() to just skip to the innermost BoundGenericType, and delegate to getSubsitutions() for the rest. Most calls to gatherAllSubstitutions() are from SILGen it seems, and fix only fixes one compiler_crasher. However an upcoming patch adds a new call to gatherAllSubstitutions() which caused some crashers to regress, so I'm going to fix it properly here. |

Fix a crasher in the archetype builder.
This particular crasher very rarely didn't crash, causing mayhem with false failures on the builders. We were keeping a reference to a vector that could be reallocated in a recursive call back into the same function. Instead, tend towards looking up the vector in the map each time we need it. |
