The current code for AssignRegisterOnReload starts the search at
the first interval instead of relying on the cached {current_interval_},
which seems to be a main cause for slow compile time in the linked
issue's test case. Moreover, it does not take into account live range
holes of the current range. This change uses FirstIntersection instead
which already handles both issues.
Since inactive ranges are sorted by their next start, we can also break
early from the loop.
