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
