9c76bbf90a Add hook in MCSection to decide when to use "optimized nops", for each 
section kind. Previously, optimized nops were only used for MachO.
Also added tests for ELF and COFF.

d03783eaf2 the immediate field of pshufw is actually an 8-bit field, not a 8-bit field that is sign extended. This fixes PR8288

49d508fd19 Jim Asked us to move DataLayout on ARM back to the most specialized classes. Do 
so and also change X86 for consistency.

Investigating if this can be improved a bit.

4599fd89fd add support for the prefetch/prefetchw instructions, move femms into 
the right file.  The assembler supports all the 3dnow instructions now,
but not the "3dnowa" ones.

8174253484 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.

e8eec016c8 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.

backing int_x86_ssse3_pshuf_w got removed.  This caused PR8280.

95581657a4 Thread the determination of branch prediction hit rates back through the if-conversion heuristic APIs. For now, 
stick with a constant estimate of 90% (branch predictors are good!), but we might find that we want to provide
more nuanced estimates in the future.

2143c9d321 Rename the AsmPrinter directory to InstPrinter for those targets that have 
been MC-ized for assembly printing. MSP430 is mostly so, but still has the
asm printer and lowering code in the printer subdir for the moment.

c14a1eda84 Massive rewrite of MMX: 
The x86_mmx type is used for MMX intrinsics, parameters and
return values where these use MMX registers, and is also
supported in load, store, and bitcast.

Only the above operations generate MMX instructions, and optimizations
do not operate on or produce MMX intrinsics. 

MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into
smaller pieces.  Optimizations may occur on these forms and the
result casted back to x86_mmx, provided the result feeds into a
previous existing x86_mmx operation.

The point of all this is prevent optimizations from introducing
MMX operations, which is unsafe due to the EMMS problem.
