82a644adf2 Remove A6/A7 opcode maps. They can all be handled with a TB map, opcode of 0xa6/0xa7, and adding MRM_C0/MRM_E0 forms. Removes 376K from the disassembler tables.

1836fe5651 Rename a DebugLoc variable to DbgLoc and a DataLayout to DL. 
This is quiet a bit less confusing now that TargetData was renamed DataLayout.

eb720cc3a1 Darwin builds: handle different possible form for SDKROOT. 
Modifying build_llvm to handle SDKROOT being the name of an SDK rather than a
path. This will still work if SDKROOT is a path.

7d2bb38164 Add an x86 prefix encoding for instructions that would decode to a different instruction with 0xf2/f3/66 were in front of them, but don't themselves have a prefix. For now this doesn't change any bbehavior, but plan to use it to fix some bugs in the disassembler.

ced2756280 Recommit r201059 and r201060 with hopefully a fix for its original failure. 
Original commits messages:

Add MRMXr/MRMXm form to X86 for use by instructions which treat the 'reg' field of modrm byte as a don't care value. Will allow for simplification of disassembler code.

Simplify a bunch of code by removing the need for the x86 disassembler table builder to know about extended opcodes. The modrm forms are sufficient to convey the information.

4c56efbd44 Provide CMake package modules in install tree 
Teach the Makefile build system to generate and install CMake modules
LLVMConfig.cmake and LLVMConfigVersion.cmake so that applications that
build with CMake can use 'find_package(LLVM)' even when LLVM is not
built with CMake.  These modules tell such applications about available
LLVM libraries and their dependencies.

Run llvm-config to generate the list of libraries and use the results of
llvm-build to generate the library dependencies.  Use sed to perform
substitutions in the LLVMConfig.cmake.in and LLVMConfigVersion.cmake.in
sources that our CMake build system uses.

Teach the Makefile build system to generate the LLVMExports.cmake file
with content similar to that produced by the CMake install(EXPORT)
command.  Extend llvm-build with an option to generate the library
dependencies fragment for this file.

c8f5d43820 LLVM-1163: AAPCS-VFP violation when CPRC allocated to stack 
According to the AAPCS, when a CPRC is allocated to the stack, all other
VFP registers should be marked as unavailable.

I have also modified the rules for allocating non-CPRCs to the stack, to make
it more explicit that all GPRs must be made unavailable. I cannot think of a
case where the old version would produce incorrect answers, so there is no test
for this.
