memcpy, memset and other intrinsics that only access their arguments
to be readnone if the intrinsic's arguments all point to local memory.
This improves the testcase in the README to readonly, but it could in
theory be made readnone, however this would involve more sophisticated
analysis that looks through the memcpy.

uses several kinds of opcode values which are not declared within
that enum. This fixes PR5946.

Add an !eq() operator to TableGen.  It operates on strings only.
Use !cast<string>() to compare other types of objects.

Have TableGen emit code that uses dbgs() rather than errs().

clear what information these functions are actually using.

This is also a micro-optimization, as passing a SDNode * around is
simpler than passing a { SDNode *, int } by value or reference.

Made LEA memory operands emit only 4 MCInst operands.
Made the scale operand equal 1 for instructions that have no
SIB byte.

Fix a bug in !subst where TableGen would go and resubstitute text it had
just substituted.  This could cause infinite looping in certain
pathological cases.

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.
