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

Add a parameter to getCopyToParts and getCopyFromParts to specify whether endian swapping should be done, and update the code to use it. This fixes some register ordering issues on big-endian systems, such as PowerPC, introduced by the recent illegal by-val arguments changes. llvm-svn: 37921

Allow remat of LI on PPC. Allow load-immediates to be rematerialised in the register coalescer for PPC. This makes test/CodeGen/PowerPC/big-endian-formal-args.ll fail, because it relies on a register move getting emitted. The immediate load is equivalent, so change this test case.
