Sanjay Patel 9615d702ad optimize vector fneg of bitcasted integer value ...

This patch allows a vector fneg of a bitcasted integer value to be optimized in the same way that we already optimize a scalar fneg. If the integer variable is a constant, we can precompute the result and not require any logic ops.

This patch is very similar to a fabs patch committed at r214892.
