Andre Vieira 1889da7048 [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.

elfcpp is a C++ library for reading and writing ELF information.  This
was written to support gold, the ELF linker, and may not be generally
useful.

elfcpp does not do file I/O.  It deals only with offsets and memory
data.

For efficiency, most accessors are templates with two arguments: the
ELF file class (32 or 64 bits) and the endianness.
