perf annotate: Add annotate_get_insn_location()

The annotate_get_insn_location() is to get the detailed information of
instruction locations like registers and offset.  It has source and
target operands locations in an array.  Each operand can have a register
and an offset.  The offset is meaningful when mem_ref flag is set.
