smartmatch: fail to find the loop instead of crashing
dopoptoloop() or dopoptolabel() would find a loop outside the sub
called from call_sv() and rewind the context and save stack to outside
the context set up by call_sv(), crashes and panics ensure.
Switching stacks here also starts a new context stack, so the outer
loop isn't found and we don't crash.
Most other callers to call_sv() (or call_method() etc) do the same.
I'm not entirely sure about passing flags = 1 to push_stackinfo(),
this matches pp_sort, but not other callers.
Fixes #16608

class.c, injected_constructor: prevent loop exits exiting
Using last, next etc would pop the context stack to above the
call_sv(), generally resulting in a crash or assertion failure.
The search the context to pop to stops at the top of the current
context stack, and PUSHSTACKi() switches to a new stack, preventing
the search from finding any loop outside the call_sv()
Similar to #16608
