This enhances the ARMAsmParser to handle .tlsdescseq directives. This is a slightly special relocation. We must be able to generate them, but not consume them in assembly. The relocation is meant to assist the linker in generating a TLS descriptor sequence. The ELF target streamer is enhanced to append additional fixups into the current segment and that is used to emit the new R_ARM_TLS_DESCSEQ relocations. llvm-svn: 200448
