David Chase 1986a450dd cmd/compile: added test to ensure that accidental fix remains
Bug 15141 was apparently fixed by some other change to the
compiler (this is plausible, it was a weird bug dependent
on a particular way of returning a large named array result),
add the test to ensure that it stays fixed.

Updates #15141.
