b68a3ee82a Second try of initial ARM/Thumb disassembler check-in. It consists of a tablgen
backend (ARMDecoderEmitter) which emits the decoder functions for ARM and Thumb,
and the disassembler core which invokes the decoder function and builds up the
MCInst based on the decoded Opcode.

Reviewed by Chris Latter and Bob Wilson.

6d1cd1cd04 Separate out the AES-NI instructions from the SSE4.2 instructions. Add
a new subtarget option for AES and check for the support.  Add "westmere"
line of processors and add AES-NI support to the core i7.

Add a couple of TODOs for information I couldn't verify.

return an error status in all failure cases, printing
messages to debugs() only when debugging is enabled.

84e679beea rename NewDebugLoc -> DebugLoc, prune #includes in DebugLoc.h.
This keeps around temporary typedef for clang/llvm-gcc so the
build won't break when I commit this :)

de4845c163 Switch the code generator (except the JIT) onto the new DebugLoc
representation.  This eliminates the 'DILocation' MDNodes for 
file/line/col tuples from -O0 -g codegen.

This remove the old DebugLoc class, making it a typedef for DebugLoc,
I'll rename NewDebugLoc next.

I didn't update the JIT to use the new apis, so it will continue to
work, but be as slow as before.  Someone should eventually do this
or, better yet, rip out the JIT debug info stuff and build the JIT
on top of MC.

255f20f7f7 Fix sdisel memcpy, memset, memmove lowering:
1. Makes it possible to lower with floating point loads and stores.
2. Avoid unaligned loads / stores unless it's fast.
3. Fix some memcpy lowering logic bug related to when to optimize a
   load from constant string into a constant.
4. Adjust x86 memcpy lowering threshold to make it more sane.
5. Fix x86 target hook so it uses vector and floating point memory
   ops more effectively.

e27e02b1a4 From Kalle Raiskila:
"the bigstack patch for SPU, with testcase. It is essentially the patch committed as 97091, and reverted as 97099, but with the following additions:
-in vararg handling, registers are marked to be live, to not confuse the register scavenger
-function prologue and epilogue are not emitted, if the stack size is 16. 16 means it is empty - there is only the register scavenger emergency spill slot, which is not used as there is no stack."
