Fix PR4789. Teach eliminateFrameIndex how to handle VLDRQ and VSTRQ which cannot fold any immediate offset.

moves. This avoids the need to promote the operands (or implicitly
extend them, a partial register update condition), and can reduce
i8 register pressure. This substantially speeds up code such as
write_hex in lib/Support/raw_ostream.cpp.

subclass-coalesce.ll is too trivial and no longer tests what it was
originally intended to test.

The instructions can be selected directly from the intrinsics.  We will need
to add some ARM-specific nodes for VLD/VST of 3 and 4 128-bit vectors, but
those are not yet implemented.

zero-extensions, also teach the h-register matching patterns that
use movzbl to match anyext as well as zext.

code hints that it would be a good idea to inline
a function ("inline" keyword).  No functional change

This fixes PR4769

llvm-svn: 80001

Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well.

This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)

the chip subdirectories, but from Chris' last mail on testing
I assume he'd rather have only one test.  Generic seems to be
the best available, maybe there should be a Darwin subdirectory?
