aarch64: Use bitreverse rtl code instead of unspec [PR115176]
Bitreverse rtl code was added with r14-1586-g6160572f8d243c. So let's
use it instead of an unspec. This is just a small cleanup but it does
have one small fix with respect to rtx costs which didn't handle vector modes
correctly for the UNSPEC and now it does.
This is part of the first step in adding __builtin_bitreverse's builtins
but it is independent of it though.
Bootstrapped and tested on aarch64-linux-gnu with no regressions.
