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.
