6500d1711a Add support to extend call operands when needed. Enable x86 fastisel call support.

6c8f55c841 Initial fastisel call support for C, Fast, and X86_FastCall calling conventions. It's meant to handle "simple" calls, i.e. no byval, structret, etc. It doesn't support multi-result returns either. 
Not yet turned on, it needs to support sext / zext of arguments and result.

ffd89d40d2 Fix X86FastISel code for comparisons and conditional branches 
to check the result of getRegForValue before using it, and
to check for illegal operand types.

50288e3c99 Add initial support for selecting constant materializations that require constant 
pool loads on X86 in fast isel.  This isn't actually used yet.

7bda51f5a4 Create HandlePHINodesInSuccessorBlocksFast, a version of 
HandlePHINodesInSuccessorBlocks that works FastISel-style. This
allows PHI nodes to be updated correctly while using FastISel.

This also involves some code reorganization; ValueMap and
MBBMap are now members of the FastISel class, so they needn't
be passed around explicitly anymore. Also, SelectInstructions
is changed to SelectInstruction, and only does one instruction
at a time.

24422d4928 Let tblgen only generate fastisel routines, not the class definition. This makes it easier for targets to define its own fastisel class.

49e19e906f Factor out the predicate check code from DAGISelEmitter.cpp 
and use it in FastISelEmitter.cpp, and make FastISel
subtarget aware. Among other things, this lets it work
properly on x86 targets that don't have SSE, where it
successfully selects x87 instructions.
