Summary:
Following patch D19265 which enable software floating point support in the Sparc backend, this patch enables the option to be enabled in the front-end using the -msoft-float option.
The user should ensure a library (such as the builtins from Compiler-RT) that includes the software floating point routines is provided.

LLVM does not and has not ever supported a soft-float ABI mode on
Sparc, so don't pretend that it does.
Also switch the default from "soft-float" -- which was actually
hard-float because soft-float is unimplemented -- to hard-float.
