Hi all,

The attached patch is a replacement for https://reviews.llvm.org/D29265. It gets rid of special treating of SoftenedFloats and normalizes softening (makes it's logic similar to promotion, expansion, e.t.c). The patch is an effort to simplify and clarify legalization and to make perhaps the first step towards using a single map for all replacements (the idea from https://reviews.llvm.org/D29265).

Please review.
