4d1dca92bd Make the disassembler tables const so they end up in read-only memory.

751752e7ca Fixed handling of immediate operand sizes, which
weren't properly reflecting the OperandSize attribute
of the instruction leading to improper decoding of
certain instructions with the 66H prefix.  Also added
a test case for this.

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.

5edca81626 Fixed a bug where the disassembler would allow an immediate
argument that had to be between 0 and 7 to have any value,
firing an assert later in the AsmPrinter.  Now, the
disassembler rejects instructions with out-of-range values
for that immediate.

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.

7c97ed7d07 Try to fix a valgrind error on 32 bit platforms: use %zu instead of %llu to format a size_t.

542eabcba6 Removed the "inline" keyword from the disassembler decoder,
because the Visual C++ build does not build .c files as C99

X86 codegen that were causing circular symbol dependencies.

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.
