x86-64: Add Intel LAM property support
Add Intel Linear Address Masking (LAM) property support. LAM modifies
the checking that is applied to 64-bit linear addresses, allowing
software to use of the untranslated address bits for metadata.
bfd/
* elf-linker-x86.h (elf_x86_cet_report): Renamed to ...
(elf_x86_prop_report): This.
(elf_linker_x86_params): Add lam_u48, lam_u57, lam_u48_report
and lam_u57_report.
* elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): Support
GNU_PROPERTY_X86_FEATURE_1_LAM_U48 and
GNU_PROPERTY_X86_FEATURE_1_LAM_U57.
(_bfd_x86_elf_link_fixup_gnu_properties): Keep LAM features only
for 64-bit output.
