I tried recording functions to be emitted during normal parsing and using it as
starting point for the final traversal. It is quite promising. I only get one
lit test failure for OpenMP:
int foobar2();
#pragma omp declare target
int (*B)() = &foobar2;
#pragma omp end declare target
int foobar2() { throw 1; } // expected-error {{cannot use 'throw' with
exceptions disabled}}
In this case, the emission state of foobar2 cannot be determined by itself. It
can only be determined to be emitted through variable B. Therefore, I also need
to record variables that are potentially emitted.
