We recently discovered an issue that reinforces what a good idea it is to always specify -mcpu in our code generation tests, particularly for -mattr=+vsx. This patch ensures that all tests that specify -mattr=+vsx also specify -mcpu=pwr7 or -mcpu=pwr8, as appropriate. Some of the uses of -mattr=+vsx added recently don't make much sense (when specified for -mtriple=powerpc-apple-darwin8 or -march=ppc32, for example). For cases like this I've just removed the extra VSX test commands; there's enough coverage without them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220173 91177308-0d34-0410-b5e6-96231b3b80d8
