Change register allocation order for ARM VFP and NEON registers to put the
...
callee-saved registers at the end of the lists. Also prefer to avoid using
the low registers that are in register subclasses required by certain
instructions, so that those registers will more likely be available when needed.
This change makes a huge improvement in spilling in some cases. Thanks to
Jakob for helping me realize the problem.
Most of this patch is fixing the testsuite. There are quite a few places
where we're checking for specific registers. I changed those to wildcards
in places where that doesn't weaken the tests. The spill-q.ll and
thumb2-spill-q.ll tests stopped spilling with this change, so I added a bunch
of live values to force spills on those tests.

Reimplement (part of) the or -> add optimization. Matching 'or' into 'add'
...
is general goodness because it allows ORs to be converted to LEA to avoid
inserting copies. However, this is bad because it makes the generated .s
file less obvious and gives valgrind heartburn (tons of false positives in
bitfield code).
While the general fix should be in valgrind, we can at least try to avoid
emitting ADD instructions that *don't* get promoted to LEA. This is more
work because it requires introducing pseudo instructions to represents
"add that knows the bits are disjoint", but hey, people really love valgrind.

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

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.

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.

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.

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.
