This API is experimental in julia 1.1 and will be replaced with
something more convenient (see #29901). In the meantime, make sure it's
clearly marked as experimental and not exported from Base.

We don't have a way to mark that the slot may contain invalid data,
so just eagerly load it so we can sanitize the value immediately
in case it is garbage.

Also some code cleanup for clarity.

This fixes a corner case where a bug is caused, counter-intuitively,
by an over-estimated intersection.
We have method signatures A and B, with A<B (A is a strict subtype).
We have a dispatch tuple X, where X<:B and !(X<:A).
However, intersection returns X for intersect(X,A). Since there
appears to be a match there and A<B, ml_matches skips the match with B.
The fix just requires dispatch tuples to be a subtype of a signature
in order to match at all.
