Some of the SHA instructions take a scalar i32 as one argument (largely because
they work on 160-bit hash fragments). This wasn't reflected in the IR
previously, with ARM and AArch64 choosing different types (<4 x i32> and <1 x
i32> respectively) which was ugly.

This makes all the affected intrinsics take a uniform "i32", allowing them to
become non-polymorphic at the same time.

ISD::BSWAP was missing from the list of node types that should be expanded
element-wise.

No functional change intended.

If pthread_get_stacksize_np() returns 512K for the main thread on Mavericks, obtain the stack size from the current stack rlimit.

encoding a specific small size. It follows the model of
SmallVectorImpl<T>.

'SmallPtrSetImplBase'. This more closely matches the organization of
SmallVector and should allow introducing a SmallPtrSetImpl which serves
the same purpose as SmallVectorImpl: isolating the element type from the
particular small size chosen. This in turn allows a lot of
simplification of APIs by not coding them against a specific small size
which is rarely needed.

-fno-function-sections is broken in Clang.

It breaks when a binary is linked with --gc-sections: parts of sanitizer
interface get thrown away and inaccessible from dlopen-ed libs.

Some lines intended to be used for testing x86_64 ABI compatibility were
not firing because lines were annotated with the wrong FileCheck prefix:
X64 vs x64

N.B. Changes beyond just changing x64 to X64 were made, presumably
because other parts of the layout engine have changed.  I've verified
the changes to make sure that MSVC creates a compatible layout.

LowerExpectIntrinsic previously only understood the idiom of an expect
