[BUILTIN] Return without arguments in a trap should use status outside traps
POSIX now requires that return without arguments in a trap should
return the last command status prior to executing traps.  This
patch implements this behaviour.

Incidentally this also changes the behaviour of return without
arguments in a loop conditional to use the last exit status in
the body as opposed to the last command in the conditional when
there is one.
