Hello,

ARMv8.2 adds a new control bit PSTATE.UAO. This patch adds support for
this bit to binutils, following the same basic pattern as for
PSTATE.PAN. The new control bit is only available when -march=armv8.2-a
is specified.

Tested aarch64-none-linux-gnu with check-binutils and check-gas.

Ok for trunk?
Matthew
