This test crashes on non-x86 host; make SSE explicit.

Feel free to fix a better way!

Add support for fast isel of (integer) immediate materialization pattens, and use them to support
...
bitcast of constants in fast isel.

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.

getelementptr doesn't work on x86-64 yet, because it

MVT::getMVT uses iPTR for pointer types, while we need the actual
...
intptr_t type in this case. FastISel can now select simple
getelementptr instructions.

demonstrate the extent of its capabilities. Note that it
only attempts to operate on one of the blocks in this
testcase.
