Assembler directives .dtprelword, .dtpreldword, .tprelword, and .tpreldword generates relocations R_MIPS_TLS_DTPREL32, R_MIPS_TLS_DTPREL64, R_MIPS_TLS_TPREL32, and R_MIPS_TLS_TPREL64 respectively. The main motivation for this patch is to be able to write test cases for checking correctness of the LLD linker's behaviour. Differential Revision: https://reviews.llvm.org/D23669 llvm-svn: 279439
