Do you have to scan the whole bb? E.g. don't or should not those
unique IFNs force end of bb?
What about adding a flag to struct function?
/* Nonzero if this function contains IFN_UNIQUE markers. */
unsigned int has_unique_calls : 1;
Then the tracer could either skip it, or do the search?
(I notice there are cilk flags already in struct function, instead of the above,
we could add an openacc-specific one with a similar behaviour?)
