c6fe3c3273 Reimplement getToken and SplitString as "StringRef helper functions" 
- getToken is modeled after StringRef::split but it can split on multiple
  separator chars and skips leading seperators.
- SplitString is a StringRef::split variant for more than 2 elements with the
  same behaviour as getToken.

78376ad7e1 Partially address a README by having functionattrs consider calls to 
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.

404a984780 Don't use the ISD::NodeType enum for SDNode opcodes, as CodeGen 
uses several kinds of opcode values which are not declared within
that enum. This fixes PR5946.

Use !cast<string>() to compare other types of objects.

ea6f91ff64 Change SelectCode's argument from SDValue to SDNode *, to make it more 
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.

04cc307edd 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.
