perf annotate: Add annotate_get_basic_blocks()

The annotate_get_basic_blocks() is to find a list of basic blocks from
the source instruction to the destination instruction in a function.

It'll be used to find variables in a scope.  Use BFS (Breadth First
Search) to find a shortest path to carry the variable/register state
minimally.

Also change find_disasm_line() to be used in annotate_get_basic_blocks()
and add 'allow_update' argument to control if it can update the IP.
