InstCombine: Only foldSelectICmpAndOr for integer types

Browse Source 
Currently foldSelectICmpAndOr asserts if the "or" involves a vector
containing several of the same power of two. We can easily avoid this by
only performing the fold on integer types, like foldSelectICmpAnd does.

Fixes <rdar://problem/15012516>
