[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. llvm-svn: 370674

[SystemZ][FPEnv] Back-end support for STRICT_[SU]INT_TO_FP As of b1d8576 there is middle-end support for STRICT_[SU]INT_TO_FP, so this patch adds SystemZ back-end support as well. The patch is SystemZ target specific except for adding SD patterns strict_[su]int_to_fp and any_[su]int_to_fp to TargetSelectionDAG.td as usual.

[FPEnv] Strict FP tests should use the requisite function attributes. A set of function attributes is required in any function that uses constrained floating point intrinsics. None of our tests use these attributes. This patch fixes this. These tests have been tested against the IR verifier changes in D68233.
