This patch adds support mvfr2 control registers for armv8-a as
this was missed from the original port to armv8-a (documented
at G6.2.109 in (Issue B.a) of the ARM-ARM. This was discovered
by an internal user of the GNU toolchain.
I'd like to backport this to the binutils 2.28 and binutils 2.29
release branch if possible (with suitable testing and basically
checking removing the armv8-r parts).
Tristan - are you ok with the backports ?
Applied to trunk.
