[binutils, ARM, 3/16] BF insns infrastructure with new bfd_reloc_code_real for fallback branch
This patch is part of a series of patches to add support for Armv8.1-M Mainline
instructions to binutils.
This adds infrastructure for the Branch Future instructions (BF, BFX, BFL, BFLX,
BFCSEL). These are the first instructions in ARM that have more than one
relocations in them.
This is the first infrastructure patch that adds a new bfd_reloc_code_real enum
for the fallback branch offset.
This is common for all such instructions and needs to be resolvable by the
assembler.
