[utils] Add Check Compile Flow Consistency tool (check_cfc.py).

This is a tool for checking consistency of code generation with different
compiler options (such as -g or outputting to .s). This tool has found a number
of code generation issues. The script acts as a wrapper to clang or clang++
performing 2 (or more) compiles then comparing the object files. Instructions
for use are in check_cfc.py including how to use with LNT.
