[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.
