In some situations Typer tries several alternatives around an inlined call. If overflow is detected at depth 32 then this could cause 2^32 different retries which leads to OOM. Prevent this with a switch that stops further inline calls as long as an overflowing call stack is not completely unwound. Fixes scala#12116
