The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.

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.
