Fold conversion to float into V4SI vsx_extract from memory.
This patch folds conversion to floating point of vsx_extract from memory of V4SI
elements where the element number is constant. This code optimizes things so it
will load the integer with LFIWAX or LFIWZX directly into a vector register
rather than loading it into a GPR and doing a direct move operation.
