That seems like a good idea but I have a doubt, 
in files like `clang/test/Analysis/plist-macros-with-expansion.cpp` , there are ~ 80 macro expansions check , there are checks for different scenarios. Will the above check suffice the intentions of the tests, in all such cases ?
( for example there are expansion checkers for `macroArgContainsCommaLParenRParenTest`, `macroArgContainsCommaInStringTest`,`CALL_FUNCTION_WITH_TWO_PARAMS`, `CALL_FUNCTION_WITH_ONE_PARAM_THROUGH_MACRO`
