Run buildCFG in disassembly in parallel

Summary:
This diff  parallelize the construction of call graph during disassembly.
The diff includes a change to  parallel-utilities where another interface
is added, that support running tasks on binaryFunctions that involves
adding instruction annotations. This pattern is common in different places,
e.g. frame optimizations. And such, pattern justify creating an interface,
that abstract out all the messy details.
