This change enables PowerPC compiler builtins to generate constrained floating point operations when clang is indicated to do so.

A couple of possibly unexpected backend divergences between constrained floating point and regular behavior are highlighted under the test tag FIXME-CHECK.  This may be something for those on the PPC backend to look at.
