[perl #122134] [jvm] for 1 { last; ENTER { say "hurz" } } leaks an UnwindException

[Christian Bartolomaeus via RT]

This works now as expected:

$ perl6-j -e 'for 1 { last; ENTER { say "hurz" } }'
hurz

I added a test to S04-phasers/in-loop.t (and unfudged the skipped tests there) 
with commit https://github.com/perl6/roast/commit/da7ff73062

I'm closing this ticket as 'resolved'.
