EMP_TEST_MACRO(MACRO, EXP_RESULT)

Input: A macro call and a strings indicating the expected result. Output: Code that tests of the macro result matches the expected results, and optionally print it (if in verbose mode or if the macro fails to produce the expected result.)

EMP_TEST_VALUE(VALUE, EXP_RESULT)

Take in an expression and a string representing the expected result; verify that the stringifyied result is the expected string AND print this info if -v flag is set. Input: An expression and an expected evaluation. Output: Code to evaluate the expression and optionally print it (if either in verbose mode or the macro does not produce the expected result).
