Where does the compiler crash?  That will normally tell you what is
needed.

The test case you showed has to do with jumping out of a nested function
to a label in an enclosing function.  This is not something that real
code does, so it's not worth worrying about unless you really want
completeness.  Look at the docs for the nonlocal_goto and
nonlocal_goto_receiver insns.  Also TRAMPOLINE_TEMPLATE and friends.
