[AArch64] Add ARMv8.2 instructions BFC and REV64.
ARMv8.2 adds two new instructions: BFC as an alias for BFM and REV64 as
an alias for REV. This patch set adds support for these to binutils,
enabled when the -march=armv8.2-a is given. It depends on the support
for an instruction being its preferred form which was added in an
earlier patch.
This patch adds the alias BFC <Rd>, #<imm>, #<width> as the preferred
form for BFM when the source is a zero register and the conditions for
using the BFI form are met (in other words, BFC is the preferred form
for BFI <Rd>, <Rs>, #<imm>, #<width> when the <Rs> is a zero register).
