[PowerPC] Support .llong and fix .word This adds support for the .llong PowerPC-specifc assembler directive. In doing so, I notices that .word is currently incorrect: it is supposed to define a 2-byte data element, not a 4-byte one. llvm-svn: 185911

[PowerPC] Generate little-endian object files 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. llvm-svn: 204634
