Why is this conditional? All targets probably ought to be using it
when raising runtime exceptions -- particularly fp exceptions.

See the comment: "which makes TCI a little faster".
When GETPC is undefined, tci.c saves an assignment
to a global variable per interpreted TCG code
which is a significant reduction.
Maybe there are better solutions, of course.
