[binutils, ARM, 8/16] BFL infrastructure with new global reloc R_ARM_THM_BF18
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 BFL instructions which is one of the first instructions in Arm that have more than one relocations in them.
This adds a new relocation R_ARM_THM_BF18.
The inconsistency between external R_ARM_THM_BF18 and internal
BFD_RELOC_ARM_THUMB_BF19 is because internally we count the static bit-0 of the immediate and we don't externally.
