As a first step towards real little-endian code generation, this patch changes the PowerPC MC layer to actually generate little-endian object files. This involves passing the little-endian flag through the various layers, including down to createELFObjectWriter so we actually get basic little-endian ELF objects, emitting instructions in little-endian order, and handling fixups and relocations as appropriate for little-endian. The bulk of the patch is to update most test cases in test/MC/PowerPC to verify both big- and little-endian encodings. (The only test cases *not* updated are those that create actual big-endian ABI code, like the TLS tests.) Note that while the object files are now little-endian, the generated code itself is not yet updated, in particular, it still does not adhere to the ELFv2 ABI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204634 91177308-0d34-0410-b5e6-96231b3b80d8
