[PATCH, binutils, ARM, 11/16] New BFCSEL instruction for Armv8.1-M Mainline

[Andre Vieira (lists)]

Hi

This patch is part of a series of patches to add support for Armv8.1-M 
Mainline instructions to binutils.

This patch adds the BFCSEL instruction. It also adds a local relocation 
with a new bfd_reloc_code_real enum.
Testing: Added new test for the valid instruction operands. Testsuite 
shows no regression when run for arm-none-eabi targets.

Thanks
Sudi
