MC: Add TargetAsmBackend::MayNeedRelaxation, for checking whether a particular instruction + fixups might need relaxation.

MC: Add TargetAsmBackend::WriteNopData and use to eliminate some target dependencies in MCMachOStreamer and MCAssembler.

MC: Tweak MCInstFragment to include the encoded data and fixups, so that we don't need to recompute them during relaxation. I will revisit this once all the other pieces of fast relaxation are in place.

DW_AT_stmt_list attribute attached with a compile unit encodes offset of line number information for this compile unit in debug_line section. This offset is always zero when only one compile unit is emitted in a object file.

MC: Fix a few more cases we were passing an MCDataFragment when a MCFragment would do, and sprinkle in some const.

Will fix correctly now that I have a testcase

MC: Change MCObjectWriter::RecordRelocation to take an MCFragment (instead of a MCDataFragment). Object files should only need the generic MCFragment features.
