Kim Phillips 58094c48f4 perf annotate: Handle arm64 move instructions
Add default handler for non-jump instructions.  This really only has an
effect on instructions that compute a PC-relative address, such as
'adrp,' as seen in these couple of examples:

BEFORE: adrp   x0, ffff20000aa11000 <kallsyms_token_index+0xce000>
AFTER:  adrp   x0, kallsyms_token_index+0xce000

BEFORE: adrp   x23, ffff20000ae94000 <__per_cpu_load>
AFTER:  adrp   x23, __per_cpu_load

The implementation is identical to that of s390, but with a slight
adjustment for objdump whitespace propagation (arm64 objdump puts spaces
after commas, whereas s390's presumably doesn't).

The mov__scnprintf() declaration is moved from s390's to arm64's
instructions.c because arm64's gets included before s390's.

Committer testing:

Ran 'perf annotate --stdio2 > /tmp/{before,after}' no diff.
