Do not inline based on @transparent in the performance inliner.
Do not inline based on @transparent in the performance inliner.

We used to do this because the mandatory inliner couldn't deal with
generics, and we were marking some things in the stdlib as @transparent
for performance reasons.

In comparing performance before/after this change, I saw noise at -Onone
and -O, and a couple differences at -Ounchecked that could be real (but
are on benchmarks that tend to be very noisy so it's hard to tell for
certain).

This change is important because I am going to commit another change
that marks protocol witness thunks as @transparent in the lead-up to
making the mandatory inliner devirtualize. I don't want that change to
generate a bunch of performance diffs and/or size diffs, which might
happen if we were to force inline *all* of those protocol witness
thunks (as opposed to the ones that will eventually be inlined by the
mandatory inliner because we're able to devirtualize the calls).
