Executor code - found an instance of a WHILE that should just be an IF

From

Hi,

During debugging I noticed some code in ExecResult() where a WHILE
loop is being used with an unconditional RETURN at the end of the
block (which is intentional, looking at the history of changes), but
now there's no actual use of the loop in any way. The code should
probably be changed to just use IF for clarity.
I've attached a patch.

Looks like leftovers from ea15e1867.

I don't think this will affect any code generation but you are right,
it should be an "if".

Since there's no bug fix here, I thought that there's not much point
in backpatching this.

Does anyone object to making this small change in master?

Indeed.  I would not bother with a back-patch either.

No objections from here.
