x86: Properly merge GNU_PROPERTY_X86_ISA_1_USED
Without the GNU_PROPERTY_X86_ISA_1_USED property, all ISAs may be used.
If a bit in the GNU_PROPERTY_X86_ISA_1_USED property is unset, the
corresponding x86 instruction set isn’t used. When merging properties
from 2 input files and one input file doesn't have the
GNU_PROPERTY_X86_ISA_1_USED property, the output file shouldn't have
it neither. This patch removes the GNU_PROPERTY_X86_ISA_1_USED
property if an input file doesn't have it.
This patch replaces the GNU_PROPERTY_X86_ISA_1_USED property with the
GNU_PROPERTY_X86_ISA_1_NEEDED property which is the minimum ISA
requirement.

* elfxx-x86.c (_bfd_x86_elf_merge_gnu_properties): Remove
GNU_PROPERTY_X86_ISA_1_USED if an input file doesn't have it.
(_bfd_x86_elf_link_setup_gnu_properties): Adding the
GNU_PROPERTY_X86_ISA_1_NEEDED, instead of
GNU_PROPERTY_X86_ISA_1_USED, property.
