perf cs-etm: Refactor instruction size handling

Browse source

This patch introduces a new function cs_etm__instr_size() to calculate
the instruction size based on ISA type and instruction address.

Given the trace data can be MB and most likely that will be A64/A32 on
a lot of platforms, cs_etm__instr_addr() keeps a single ISA type check
for A64/A32 and executes an optimized calculation (addr + offset * 4).
