Enhance dead store checker to not flag preincrements to dead variables where the preincrement is a subexpression, e.g. foo(++x); This can cause false negatives, but will remove a whole class of false positives.

Some minor cleanups:
...
1. Compute action in X86SelectSelect based on MVT instead of type.
2. Use TLI.getValueType(..) instead of MVT::getVT(..) because the former
handles pointers and the later doesn't.
3. Don't pass TLI into isTypeLegal, since it already has access to it as
an ivar.
#2 gives fast isel some minor new functionality: handling load/stores of
pointers.

refactor compare emission out into a new X86FastEmitCompare method,

This shaves a bunch of instructions off the common select case, which
happens a lot in llvm-gcc.

- Add target lowering hooks that specify which setcc conditions are illegal,
...
i.e. conditions that cannot be checked with a single instruction. For example,
SETONE and SETUEQ on x86.
- Teach legalizer to implement *illegal* setcc as a and / or of a number of
legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is
implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ.
- Move x86 target over.

Simplify handling of struct/union/class tags.
...
Instead of using two sets of Decl kinds (Struct/Union/Class and CXXStruct/CXXUnion/CXXClass), use one 'Record' and one 'CXXRecord' Decl kind and make tag kind a property of TagDecl.
Cleans up the code a bit and better reflects that Decl class structure.
