Sema was creating DerivedFileUnit on the fly, while something else is iterating
over FileUnits in the module. The fix is to create DerivedFileUnit in advance.
This change immediately uncovered a lot of code that assumed that the module
consists of a single FileUnit at certain conditions. This patch also fixes
that code (SourceKit patch is separate, not sending it).
The test change is because now operator == on NSObjects is correctly recognised
as coming from a system module.

If an enum has no cases with payloads, make it implicitly Equatable and Hashable, and derive default implementations of '==' and 'hashValue'. Insert the derived '==' into module context wrapped in a new DerivedFileUnit kind, and arrange for it to be codegenned with the deriving EnumDecl by adding a 'DerivedOperatorDecls' array to NominalTypeDecls that gets visited at SILGen time.

Normally, protocol conformances are only checked for types and extensions
declared in the current file. However, for protocols that can derive their
conformances (like RawRepresentable), other files in the target might
expect to be able to use the protocol members (like toRaw), which aren't
written in the source. Force the derivation if this is the case.
Also, move the /other/ set of RawRepresentable tests from test/Parse to
test/Sema.

This has the nice "side effect" of making overrides of generic
functions work better, fixing the remaining type checker issues from
<rdar://problem/15836098>.
Also synthesize the types for derived RawRepresentable conformances
directly rather than going through the type checker, so we get the
interface types right.

now that they are implicitly updated. This exposes two things:
1) we're unncessarily serializing selfdecls in ctors and dtors.
2) The index pattern of a SubscriptDecl has no sensible DeclContext that
owns variables in it.
I'll deal with the first tomorrow, I'm not sure what to do with
the second one.

ArraySliceType::get, OptionalType::get, and a few
other places.
There is more to be done here, but this is all I plan to do
for now.

...rather than a raw pointer that points to a buffer with space for N
elements. Just because we *can* get N from context doesn't mean it's
convenient/safe.
No functionality change.

typealias MyInt: ForwardIndex = Int
There is no real reason to allow this; it's just a static_assert that Int
conforms to ForwardIndex, which would be better spelled some other way.
This only applies to concrete typealiases, i.e. those that simply alias an
underlying type. Associated types can still have both inheritance clauses
and a (default) underlying type.

Before, the synthesized bodies were immediately fed into the type-checker.
However, it's possible the bodies could reference something that hasn't yet
been deserialized. Type-check them along with other implicitly-generated
declarations at the end of type-checking.

places, but not the particularly interesting or useful places yet.

Previously, the Parser and BranchStmt typedef-ed ExprStmtOrDecl as a pointer union. Using typedef made the objects compatible, but did not allow us to extend the type with helper methods, such as getSourceRange(), which is something you can get on all of the AST objects. This patch introduces ASTNode that subclasses from PointerUnion and is used by both parser and BranchStmt.

I tried hard find all references to 'func' in documentation, comments and
diagnostics, but I am sure that I missed a few. If you find something, please
let me know.

Currently integer literals are 64-bit. In order to allow checking for overflow
while converting an integer literal to swift.UInt/Int* types we need at least
65 bits. But floating point numbers (Float32, Float64, Float80) are
BuiltinIntegerLiteralConvertible. In order to allow spelling large floating
point constants, we allow 136-bit literals.
Rationale: 128 bits are enough to represent the absolute value of min/max IEEE
Binary32, and we need 1 bit to represent the sign. 136 is 129 rounded to the
next 8 bits.
The plan is to have builtins that do the overflow check and convert 136-bit
numbers to the required width. We need these builtins for both integers and
floating point numbers to ensure that 136-bit numbers are folded into sane
constants in SIL and don’t escape to LLVM IR.

Non-generic functions within a generic nominal type have generic
signatures, because their curried 'self' arguments are of bound
generic type.

For derivable protocols, such as RawRepresentable on raw-typed enums, when checking the conformance, create a conforming decl if an explicit decl wasn't found. Refactor the conformance derivation for toRaw/fromRaw to be driven by conformance checking in this way.
Swift SVN r8930
If an enum has a valid raw type, synthesize a RawType associated type along with fromRaw and toRaw methods.
An implicit conformance to RawRepresentable is not yet set up. This synthesis may need to be done earlier in order for the names to be available during type-checking of definitions in the enum too.
