Simplify fp tests now checking the simplified GOTO

Due to high variation in the number of generated goto statements on
different platforms, checking specific number simplified is unreliable.
This changes the tests to first simplify then spit out the generated
GOTO code. This is then checked to check the if statements generated by
function pointer removal is removed by the simplify step

 Check the GOTOs generated by the function pointer removal are removed by the
 simplify step. This requires supporting tracking arrays assigned dynamically
