perf annotate: Add per arch instructions annotate handlers
Another step in supporting cross annotation.
The arch specific tables are put in:
tools/perf/arch/$ARCH/annotation/instructions.c
which, so far, just plug instructions to a bunch of parsers/formatters,
but may have more as the need arises.
This is an alternative implementation to a previous attempt made by Ravi
Bangoria.
