Fix a bad error in tcMatchTywip/T17395
This patch fixes #17395, a very subtle and hard-to-trigger
bug in tcMatchTy. It's all explained in
Note [Matching in the presence of casts (2)]
I have not added a regression test because it is very hard
to trigger it, until we have the upcoming mkAppTyM patch,
after which lacking this patch means you can't even compile
the libraries.
