DWARF emission: Remove unnecessary/redundant DIE reference code

The default case at the end of the switch handles this just fine.

lto.h: Use lto_bool_t instead of int to restore the ABI

This reverts commit r193255 and instead creates an lto_bool_t typedef
that points to bool, _Bool, or unsigned char depending on what is
available.  Only recent versions of MSVC provide a stdbool.h header.

MCStreamer: Reimplement the virtual EmitRawText as a protected member, EmitRawTextImpl, to avoid string literal ambiguities

Also improve the implementation of EmitRawText(Twine) so it doesn't
bother using the SmallString buffer if the Twine is a simple StringRef
anyway.

ARM: Tweak usage of '*vfp' compiler_rt functions.

Only use them if the subtarget has ARM mode, as these routines are implemented
as ARM code.

ARM: Test r193381 a bit more thoroughly.

Make sure we're predicating right based on CPU even if the triple is 'wrong'.

Support for reading program counts in llvm-cov.

llvm-cov will now be able to read program counts from the GCDA file and
output it in the same format as gcov. The program summary tag was
identified from gcov-io.h as "\0\0\0\a3".

There is currently a bug in GCOVProfiling.cpp which does not generate
the
run- or program-counting IR, so this change was tested manually by
modifying the GCDA file and comparing the gcov and llvm-cov outputs.

Optimize concat_vectors(X, undef) -> scalar_to_vector(X).
This optimization is not SSE specific so I am moving it to DAGco.
The new scalar_to_vector dag node exposed a missing pattern in the AArch64 target that I needed to add.

ARM: tweak test to pass on all platforms

A TableGen indeterminacy means that the reason for the failure can
vary, and Windows gets the other option.
