PowerPC: Do not use llc -march in tests. `llc -march` is problematic because it only switches the target architecture, but leaves the operating system unchanged. This occasionally leads to indeterministic tests because the OS from LLVM_DEFAULT_TARGET_TRIPLE is used. However we can simply always use `llc -mtriple` instead. This changes all the tests to do this to avoid people using -march when they copy and paste parts of tests. This patch: - Removes -march if the .ll file already has a matching `target triple` directive or -mtriple argument. - In all other cases changes -march=ppc32/-march=ppc64 to -mtriple=ppc32--/-mtriple=ppc64-- See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309754

[PowerPC] Enable printing instructions using aliases TableGen had been nicely generating code to print a number of instructions using shorter aliases (and PowerPC has plenty of short mnemonics), but we were not calling it. For some of the aliases we support in the parser, TableGen can't infer the "inverse" alias relationship, so there is still more to do. Thus, after some hours of updating test cases... llvm-svn: 235616
