@inout parameters can be nocapture and dereferenceable. @in, @in_guaranteed, and indirected @direct parameters can be noalias, nocapture, and dereferenceable.

It's not worth burning more than three registers on a parameter, and doing so causes code size issues for large structs and enums. Make it so that values with more than three explosion members get passed indirectly, just like they get returned indirectly.
This time, modify emitPartialApplyForwarder not to attempt to 'tail' call the original function when indirect arguments get alloca'ed on the stack, which is UB, and don't use "byval", as suggested by John.

All llvm::Functions created during IRGen will have target-cpu and target-features
attributes if they are non-null.
Update testing cases to expect the attribute in function definition.
Add testing case function-target-features.swift to verify target-cpu and
target-features.

This lets us disambiguate the symbols for static and instance properties, and enables us to eventually leave the useless "self" type mangling out of method symbols. Fixes rdar://19012022 and dupes thereof, including crasher #1341.

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.

Doing so is safe even though we have mock SDK. The include paths for
modules with the same name in the real and mock SDKs are different, and
the module files will be distinct (because they will have a different
hash).
This reduces test runtime on OS X by 30% and brings it under a minute on
a 16-core machine.
This also uncovered some problems with some tests -- even when run for
iOS configurations, some tests would still run with macosx triple. I
fixed the tests where I noticed this issue.

-enable-source-import doesn't play nice with debug info, and we want to be
able to run all tests with -g added. The last few tests that require
-enable-source-import could be built with --no-debug-info, or however we
end up spelling that.

This is needed for tests which define internal functions which should not be eliminated.
So far this was not needed because of a hack which prevented whole-module-optimizations for tests.

Teaches TryAddFinal to descend into public and objc classes. Only
tries to add final if we're either whole compilation mode, or we're
processing the primary source buffer.
Updates test cases. Includes workarounds for <rdar://problem/17860781>
and <rdar://problem/17862348>.

Instead of hacking together inaccurate metadata only for object-typed properties, make an effort to produce accurate metadata for all types of properties, and accurately capture the "copy", "dynamic", and "weak" semantics of some properties. This is necessary for Core Data to accurately synthesize property accessors for non-object properties; currently it will generate bogus object accessors over properties with non-object type. <rdar://problem/17373368>
This isn't fully accurate, since Clang hides property type encoding behind a 'getObjCEncodingForPropertyDecl' that only accepts an ObjCPropertyDecl. With some refactoring, it should be possible to expose this.
