This makes it much more useful for running benchmarks that are missing
prototypes for some functions.

char *malloc();
void free();

to forward declare malloc and free.  Now we recognize and raise these forms

Support function declarations with either %XXX or "XXX" style for now
"XXX" style should be considered deprecated, and will hopefully be removed
in the future.
