A couple of Aarch64 FIPS delocate fixes.

Clang 12 in opt mode produces a couple of assembly patterns that were
not handled by delocate.

Firstly, two-digit vector indexes were just a simple omission. Fixed.

Secondly, Clang puts symbol deltas in .byte directives, and bit-shifts
them. The .byte directive was not considered to be a symbol-containing
directive because it's too small, but it could store deltas.
Additionally, bit-shifting of symbol expressions was not supported.
Fixed.
