Force a triple on a couple of tests; we don't support fast-isel of ret on Win64.

Add -mattr=+sse2 to the -march=x86 version of this test. Without
...
sse, this code falls back to SelectionDAG isel which uses an x87
instruction, which is fine, but not what this test is testing for.

isn't legal.

Fix a thinko: When lowering fneg with xor, bitcast the operands
...
from floating-point to integer first, and bitcast the result
back to floating-point. Previously, this test was passing by
falling back to SelectionDAG lowering. The resulting code isn't
as nice, but it's correct and CodeGen now stays on the fast path.

LLVM currently represents floating-point negation as -0.0 - x. Fix
...
FastISel to recognize this pattern and emit a floating-point
negation using xor.
