fd06aa7c07 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.

3d45a853db LLVM currently represents floating-point negation as -0.0 - x. Fix
FastISel to recognize this pattern and emit a floating-point
negation using xor.
