[binutils, ARM, 10/16] BFCSEL infrastructure with new global reloc R_ARM_THM_BF12
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 BFCSEL 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_BF12.
The inconsistency between external R_ARM_THM_BF12 and internal
BFD_RELOC_ARM_THUMB_BF13 is because internally we count the static bit-0 of the
immediate and we don't externally.
