aarch64: Add new relocations and limit COFF AArch64 relocation offsets
The patch adds support for the IMAGE_REL_ARM64_REL32 coff relocation
type. This is needed for 32-bit relative address.
It also adds a check for relocation offsets over 21 bits. Offsets
inside coff files are stored in instruction code. In the case of ADRP
the actual value is stored, not a downshifted page offset. This means
values over 21 bits would otherwise be truncated.
Finally it adds a mapping for BFD_RELOC_AARCH64_ADR_GOT_PAGE and
BFD_RELOC_AARCH64_LD64_GOT_LO12_NC that were previously skipped.
ChangeLog:
* bfd/coff-aarch64.c (coff_aarch64_reloc_type_lookup): Add
BFD_RELOC_AARCH64_ADR_GOT_PAGE,
BFD_RELOC_AARCH64_LD64_GOT_LO12_NC and IMAGE_REL_ARM64_REL32
relocations.
(coff_pe_aarch64_relocate_section): Likewise.
* gas/write.c (adjust_reloc_syms): COFF AArch64 relocation
offsets need to be limited to 21bits
(defined): Likewise.
