non-blocking: could we clarify the behavior when an ENTRY has a different dummy list? For `subroutine s(x)` with `declare simd linear(x:1)` and `entry e(y)`, the op emitted for `e` refers to `x`, which is not its parameter. OpenMP requires `linear`/`uniform` items on `declare simd` clause items to be parameters of the associated procedure. Should the directive propagate to such entries, and could we add this case to the test?
