Subject: perf annotate: Improve support for ARM

By using arch->init() to set up some regular expressions to associate
ins_ops to ARM instructions, ditching that old table that has
instructions not present on ARM.

Take advantage of having an arch->init() to hide more arm specific stuff
from the common code, like the objdump details.

The regular expressions comes from a patch written by Kim Phillips.
