548abfcbd6 Implement support for the bizarre 3DNow! encoding (which is unlike anything
else in X86), and add support for pavgusb.  This is apparently the
only instruction (other than movsx) that is preventing ffmpeg from building
with clang.

If someone else is interested in banging out the rest of the 3DNow! 
instructions, it should be quite easy now.

75e2016f02 Remove two uses of the gcc specific 'aligned' attribute. This
is partly because this attribute caused trouble in the past (the
SmallVector one had to be changed from aligned to aligned(8) due
to causing crashes on i386 for example; in theory the same might
be needed in the Allocator case...).  But it's mostly because
there seems to be no point in special casing gcc here.  Using the
same implementation for all compilers results in better testing.

ec45f60cab Major changes to Cortex-A9 itinerary.
1. Model dual issues as two FUs.
2. Model the pipelines correctly: two symmetric ALUs, the multiplier is a
   dependent pipeline on ALU0.
The changes do not have much impact on codegen right now. But I plan to make
pre-RA scheduler multi-issue aware which should take good advantage of the
changes.

f70007e89e Fix a miscompile in 186.crafty for Thumb2 that was exposed by Evan's
scheduling change in svn 115121.  The CriticalAntiDepBreaker had bad
liveness information.  It was calculating the KillIndices for one scheduling
region in a basic block, rescheduling that region so the KillIndices were
no longer valid, and then using those wrong KillIndices to make decisions
for the next scheduling region.  I've not been able to reduce a small
testcase for this.  Radar 8502534.

8c9aa922a9 This adds a Darwin x86_64 relocation encoding for a subtraction expression
where both symbols are "local", that is non-external symbols, and there is
no "base" for the symbols used in the expression, that is the section has
no non-temporary symbols.  This case looks like this:

% cat local_reloc_A-B.s
	.long 0
LB:	.long 1
	.long LA - LB - 4
	.long 2
LA:	.long 3

which llvm-mc will not encode without this patch, generates a "unsupported
local relocations in difference" error, but the Darwin assembler will
encode with relocation entries like this:

% otool -rv a.out l.out 
a.out:
Relocation information (__TEXT,__text) 2 entries
address  pcrel length extern type    scattered symbolnum/value
00000008 False long   False  SUB     False     1 (__TEXT,__text)
00000008 False long   False  UNSIGND False     1 (__TEXT,__text)

which is very similar to what is encoded when the symbols don't have the
leading 'L' and they are not temporary symbols.  Which llvm-mc and the
Darwin assembler will encoded like this:

Relocation information (__TEXT,__text) 2 entries
address  pcrel length extern type    scattered symbolnum/value
00000008 False long   True   SUB     False     B
00000008 False long   True   UNSIGND False     A

This is the missing relocation encoding needed to allow the Mach-O x86
Dwarf file and line table to be emitted.  So this patch also removes the
TODO from the if() statement in MCMachOStreamer::Finish() that didn't 
call MCDwarfFileTable::Emit() for 64-bit targets.

e0a73ec0a9 When RemoveCopyByCommutingDef is creating additional identity copies, just use
LiveInterval::MergeValueNumberInto instead of trying to extend LiveRanges and
getting it wrong.

This fixed PR8249 where a valno with a multi-segment live range was defined by
an identity copy created by RemoveCopyByCommutingDef. Some of the live
segments disappeared.
