1a8b789a4b Eliminated the classification of control registers into %ecr_
and %rcr_, leaving just %cr_ which is what people expect.
Updated the disassembler to support this unified register set.
Added a testcase to verify that the registers continue to be
decoded correctly.

a144c3f34d Fixes to the X86 disassembler. The disassembler will now
return an error status in all failure cases, printing
messages to debugs() only when debugging is enabled.

5227cc89f4 More fixes for Visual C++. Replaced several very small
static inline functions with macros.

06b766d1c0 Changed REG_* to MODRM_REG_* to avoid conflicts
with symbols in AuroraUX's global namespace.

8ed9f51663 Table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit
incarnations), integrated into the MC framework.  

The disassembler is table-driven, using a custom TableGen backend to 
generate hierarchical tables optimized for fast decode.  The disassembler 
consumes MemoryObjects and produces arrays of MCInsts, adhering to the 
abstract base class MCDisassembler (llvm/MC/MCDisassembler.h).

The disassembler is documented in detail in

- lib/Target/X86/Disassembler/X86Disassembler.cpp (disassembler runtime)
- utils/TableGen/DisassemblerEmitter.cpp (table emitter)

You can test the disassembler by running llvm-mc -disassemble for i386
or x86_64 targets.  Please let me know if you encounter any problems
with it.
