scanner: compute token line/column lazily on errors
The scanner functions are hot, and the line/column location tracking is
quite expensive. We only use it for errors, which don't need to be fast,
because we bail if there are too many; and for warnings, which are
usually not shown by default. So only keep the token start pos, and
compute the line/column lazily from that. This will also allow some
further improvements ahead.
