Ulrich Weigand b21e245711 [SystemZ] Support constrained fpto[su]i intrinsics
Now that constrained fpto[su]i intrinsic are available,
add codegen support to the SystemZ backend.

In addition to pure back-end changes, I've also needed
to add the strict_fp_to_[su]int and any_fp_to_[su]int
pattern fragments in the obvious way.
