Sanjay Patel 05527b68a0 [InstCombine] fold more shuffles with FP<->Int cast operands ...

shuffle (cast X), (cast Y), Mask --> cast (shuffle X, Y, Mask)

This extends the transform added with 0353c2c996.

If the shuffle reduces vector length, the transform
reduces the width of the cast, so that should be a
win for most codegen (if not, it can be inverted).
