We also use direct moves when converting integers to FP. When these operations are chained, we get a direct move out of a VSR followed by a direct move back into a VSR. These are redundant - all we need to do is line up the element and convert. llvm-svn: 275796	2016-07-18 15:30:00 +00:00

[PowerPC] Remove redundant direct moves when extracting integers and converting to FP

We use direct moves for extracting integer elements from vectors. We also use
direct moves when converting integers to FP. When these operations are chained,
we get a direct move out of a VSR followed by a direct move back into a VSR.
These are redundant - all we need to do is line up the element and convert.
