[SystemZ] Support z15 processor name The recently announced IBM z15 processor implements the architecture already supported as "arch13" in LLVM. This patch adds support for "z15" as an alternate architecture name for arch13. The patch also uses z15 in a number of places where we used arch13 as long as the official name was not yet announced. llvm-svn: 372435

; Test strict conversions between integer and float elements on z15.
[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
