CL 342350 fixed panic with dead hidden closures, by marking discarded
hidden closure as dead, and won't compile them. However, the fix is
incomplete. In case the "if" or "else" block end with panic or return
statement:
if true { return }
# All nodes starts from here are dead
the dead nodes must be processed with markHiddenClosureDead, but they
are not, causing the compiler crashes.
This CL adds that missing part.
Fixes #48459
