[legalize-types] Clean up softening machinery. The patch makes SoftenFloatResult/Operand logic just the same as all other legalization routines have: SoftenFloatResult() now fills the SoftenFloats map and SoftenFloatOperand() perform all needed replacements. This prevents softening mashinery from leaving stale entries in SoftenFloats map (that resulted in errors during the legalize type checking) and clarifies softening. The patch replaces https://reviews.llvm.org/D29265. Differential Revision: https://reviews.llvm.org/D31946 llvm-svn: 307053

; Check that we dont end up with the ""LLVM ERROR: Cannot select" error.
; Additionally ensure that the output code actually put fp128 values in SSE registers.
