[ARM] Support ARMv8.2 RAS extension.
The ARMv8.2 architecture includes the RAS extension which adds an instruction, ESB, and a number of coprocessor registers. This patch adds the instruction to binutils, making it available when -march=armv8.2-a is selected. It also adds tests for the instruction and for the coprocessor registers. gas/ 2016-01-12 Matthew Wahab <matthew.wahab@arm.com> * config/tc-arm.c (arm_ext_v8_2): New.
