Reverse sense of WHILE/UNTIL in Pass1T

copy Signal types for catchphrase arms, do the right thing about context level for the input and output contexts.

Make sure catches put in explicit REJECT at end.

retain declitem nodes (don't rewrite initializations as assignment)
safen non-local return values from entry procs (Pass3s).
