[VECTOR-SELECT]
During type legalization we often use the SIGN_EXTEND_INREG SDNode.
When this SDNode is legalized during the LegalizeVector phase, it is
scalarized because non-simple types are automatically marked to be expanded.
In this patch we add support for lowering SIGN_EXTEND_INREG manually.
This fixes CodeGen/X86/vec_sext.ll when running with the '-promote-elements'
flag.

Fix up assertion in r135018 so it doesn't trigger on 32-bit; when we're in 32-bit, it doesn't matter whether the operation overflows because the computed address is not wider than the immediate.

The frameless unwind stack has a special encoding, the algorithm for which is in

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.

Refactor out checking for displacements on x86-64 addressing modes.  No functionality change.  Refactoring in preparation for an additional safety check in FoldOffsetIntoAddress.

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.

  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.

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.

Really force on 64bit for 64-bit targets.  Should fix remaining failures on unknown x86/non-x86 targets.

Revert earlier unnecessary hack.  Make sure we correctly force on 64bit and cmov for 64-bit targets.

- 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".
