Handle the following relocations related to TLS local-exec and initial-exec: - R_RISCV_TLS_GOT_HI20 - R_RISCV_TPREL_HI20 - R_RISCV_TPREL_ADD - R_RISCV_TPREL_LO12_I - R_RISCV_TPREL_LO12_S In addition, GNU ld has a quirk where after TLS le relaxation, two unofficial relocation types may be emitted: - R_RISCV_TPREL_I - R_RISCV_TPREL_S Since they are unofficial (defined in the reserved range of relocation types), LLVM does not define them. Hence, I've defined them locally in BOLT in a private namespace.
