[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.
