[PATCH, AArch64] Reinstate R_AARCH64_TLS_DTPMOD64, R_AARCH64_TLS_DTPREL64 and R_AARCH64_TLS_TPREL64

[Yufeng Zhang <Yufeng dot Zhang at arm dot com>]

Hi,

R_AARCH64_TLS_DTPMOD64, R_AARCH64_TLS_DTPREL64 and R_AARCH64_TLS_TPREL64 
were previously renamed to R_AARCH64_TLS_DTPMOD, R_AARCH64_TLS_DTPREL 
and R_AARCH64_TLS_TPREL respectively during the implementation of the 
ILP32 support.  The latest revision of the AAELF64 document decides to 
re-instate the original relocation names in order to preserve 
backward-compatibility.  This patch adds them back.  One step beyond the 
specification, R_AAARCH64_TLS_DTPREL, R_AAARCH64_TLS_DTPMOD and 
R_AAARCH64_TLS_TPREL are kept in the current gas/binutils implementation 
as aliasing names.  This helps keep the code a bit neat.  Note that we 
have R_AAARCH64_P32_TLS_DTPREL, R_AAARCH64_P32_TLS_DTPMOD and 
R_AAARCH64_P32_TLS_TPREL for the corresponding ILP32 ABI.

OK for the mainline and 2_24 branch?

Thanks,
Yufeng

        * elfnn-aarch64.c (elfNN_aarch64_howto_table): Use
        R_AARCH64_TLS_DTPMOD64 instead of R_AARCH64_TLS_DTPMOD;
        likewise for R_AARCH64_TLS_DTPREL and R_AARCH64_TLS_TPREL.

include/elf/

        * include/elf/aarch64.h: Define R_AARCH64_TLS_DTPMOD64,
        R_AARCH64_TLS_DTPREL64 and R_AARCH64_TLS_TPREL64; guard
        R_AARCH64_TLS_DTPMOD, R_AARCH64_TLS_DTPREL and
        R_AARCH64_TLS_TPREL with RELOC_MACROS_GEN_FUNC.
