the predicates by extending simple predicates to create
more complex predicates instead of duplicating the logic
for the simple predicates.

This doesn't reduce much redundancy in DAGISelEmitter.cpp's
generated source yet; that will require improvements to
DAGISelEmitter.cpp's instruction sorting, to make it more
effectively group nodes with similar predicates together.

them since they map to insert element

This will allow predicates to be composed, which will allow the
predicate definitions to become less redundant, and eventually
will allow DAGISelEmitter.cpp to emit less redundant code.

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.

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.

This shaves a bunch of instructions off the common select case, which

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.

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.
