[LD][AARCH64]Add group relocations to create PC-relative offset. This is a patch to add linker support for group relocations to create a 16, 32, 48, or 64 bit PC-relative offset inline. The following relocations are added along with the test cases: BFD_RELOC_AARCH64_MOVW_PREL_G0, BFD_RELOC_AARCH64_MOVW_PREL_G0_NC, BFD_RELOC_AARCH64_MOVW_PREL_G1, BFD_RELOC_AARCH64_MOVW_PREL_G1_NC, BFD_RELOC_AARCH64_MOVW_PREL_G2, BFD_RELOC_AARCH64_MOVW_PREL_G2_NC, BFD_RELOC_AARCH64_MOVW_PREL_G3. bfd/ 2018-01-24 Renlin Li <renlin.li@arm.com> * elfnn-aarch64.c (elfNN_aarch64_final_link_relocate): Add support for BFD_RELOC_AARCH64_MOVW_PREL_G0, BFD_RELOC_AARCH64_MOVW_PREL_G0_NC, BFD_RELOC_AARCH64_MOVW_PREL_G1, BFD_RELOC_AARCH64_MOVW_PREL_G1_NC, BFD_RELOC_AARCH64_MOVW_PREL_G2, BFD_RELOC_AARCH64_MOVW_PREL_G2_NC, BFD_RELOC_AARCH64_MOVW_PREL_G3. * elfxx-aarch64.c (_bfd_aarch64_elf_put_addend): Likewise.
