[PATCH] [PATCH] FastISel fixes with FeatureVSX enabled

[Bill Schmidt]

I've been thinking about this a bit more, and I'm not very happy with a solution that changes the general FastISel machinery, given that it's intended to be temporary.  I think seurer is making pretty good progress on the real solution for VSX in FastISel, so it might be best to suck it up and wait for that to be completed.  Thoughts?

BTW, from a note he sent me this morning I have a feeling that FastISel may be ignoring AddedComplexity in the pattern selection code.  The VSX pattern should be preferred over the other when available, but the non-VSX pattern code is being generated first, which doesn't give the VSX pattern a chance.  Eric, is this possible?
