Previously type sizes would be inconsistently sourced from either the LLVM type
or the FixedTypeInfo, depending on the call site. This was problematic because
TypeInfo operates with a resolution of whole bytes, which means that types such
as i1 would get a reported as having a size of 8. This patch now asserts that
all occurrences of the same type have the same size as the first, cached
occurence.
To avoid triggering the cached type verification assertion, this patch avoids
caching of storage-sized containers. It also removes the unique identifier from
forward declarations, which could lead to type confusion during LTO.

Admit different path separators in DebugInfo tests. These will be used
in subsequent changes that enable the directory module layout on
non-Darwin platforms.
This patch changes the DWARF representation of bound generic struct to a nested
struct where the (sized) outer struct is anonymous and thus distinct and the
inner struct in uniqued and sizeless.
This is anologous the the previous commit that did the same thing for bound
generic enums.

This changes the Swift resource directory from looking like
lib/
swift/
macosx/
libswiftCore.dylib
libswiftDarwin.dylib
x86_64/
Swift.swiftmodule
Swift.swiftdoc
Darwin.swiftmodule
Darwin.swiftdoc
to
lib/
swift/
macosx/
libswiftCore.dylib
libswiftDarwin.dylib
Swift.swiftmodule/
x86_64.swiftmodule
x86_64.swiftdoc
Darwin.swiftmodule/
x86_64.swiftmodule
x86_64.swiftdoc
matching the layout we use for multi-architecture swiftmodules
everywhere else (particularly frameworks).
There's no change in this commit to how Linux swiftmodules are
packaged. There's been past interest in going the /opposite/ direction
for Linux, since there's not standard support for fat
(multi-architecture) .so libraries. Moving the .so search path /down/
to an architecture-specific directory on Linux would allow the same
resource directory to be used for both host-compiling and
cross-compiling.

This applies the same changes from Clang CFE r349065 to the Swift
frontend to unify how filenames, cmpilation directories and absolute
paths in filenames and path remappings are handled.
Assembly generated for ARM uses `%` to prefix section types, as opposed to
the typical `@`. On ARM, `@` has historically been used for comments.
Fix the test when run targeting ARM, by accepting both.
There's still work left to do. In terms of next steps, there's still rdar://problem/22126141, which covers removing the 'workaround' overloads for print (that prevent bogus overload resolution failures), as well as providing a decent diagnostic when users invoke print with 'appendNewline'.

MDModule was a bitcode-incompatible internal-only extension that has
since been replaced with a blessed IR node on trunk.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.

Eliminate the intermediate top_level_code function. Now that SIL is expressive enough to express a "main" function, there's no reason for it, and this eliminates a bunch of mystery code in IRGen to thunk from main to top_level_code by reaching for hardcoded symbol names. Demystify the special code for setting up C_ARGC and C_ARGV by having SILGen look for a transparent "_didEnterMain" hook in the stdlib and emit a call to it.

Introduce the new BooleanLiteralConvertible protocol for Boolean
literals. Take "true" and "false" as real keywords (which is most of the
reason for the testsuite churn). Make Bool BooleanLiteralConvertible
and the default Boolean literal type, and ObjCBool
BooleanLiteralConvertible. Fixes <rdar://problem/17405310> and the
recent regression that made ObjCBool not work with true/false.

- DebugTypeInfo holds all type info we need to emit debug information.
- Type info is limited to name, location, and storage size.
- As a side-effect: verbose LLVM IR allocas in debug builds!
