466b022c99 Make X86ISD::ANDNP more general and Codegen 256-bit VANDNP. A more 
general version of X86ISD::ANDNP also opened the room for a little bit
of refactoring.

c1af4772f1 The target specific node PANDN name is misleading. That happens because 
it's later selected to a ANDNPD/ANDNPS instruction instead of the PANDN
instruction. Rename it.

2a01946de4 Make sure we don't combine a large displacement and a frame index in the same addressing mode on x86-64. It can overflow, leading to a crash/miscompile.

b7f689bab9 Update MCParsedAsmOperand debug methods. 
Update the debug output interface for MCParsedAsmOperand to have a print()
method which takes an output stream argument, an << operator which invokes
the print method using the given stream, and a dump() method which prints
the operand to the dbgs() stream. This makes the interface more consistent
with the rest of LLVM, and more convenient to use at the debugger command
line.

595d745f5f Clean up the handling of an EBP/RBP unwind frame pointer. In particular, don't 
assert when the frame pointer is -1 (i.e., the function is "frameless").

Still to do: "frameless" unwind information.

59ee62d241 - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfo 
and MCSubtargetInfo.
- Added methods to update subtarget features (used when targets automatically
  detect subtarget features or switch modes).
- Teach X86Subtarget to update MCSubtargetInfo features bits since the
  MCSubtargetInfo layer can be shared with other modules.
- These fixes .code 16 / .code 32 support since mode switch is updated in
  MCSubtargetInfo so MC code emitter can do the right thing.

ffc0e73046 Change createAsmParser to take a MCSubtargetInfo instead of triple, 
CPU, and feature string. Parsing some asm directives can change
subtarget state (e.g. .code 16) and it must be reflected in other
modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance
must be shared.

ebdeeab812 Eliminate asm parser's dependency on TargetMachine: 
- Each target asm parser now creates its own MCSubtatgetInfo (if needed).
- Changed AssemblerPredicate to take subtarget features which tablegen uses
  to generate asm matcher subtarget feature queries. e.g.
  "ModeThumb,FeatureThumb2" is translated to
  "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0".
