  [clang] Properly cache member pointer LLVM types

When not going through the main Clang->LLVM type cache, we'd
accidentally create multiple different opaque types for a member pointer
type.

This allows us to remove the -verify-type-cache flag now that
check-clang passes with it on. We can do the verification in expensive
builds. Previously microsoft-abi-member-pointers.cpp was failing with
-verify-type-cache.

I suspect that there may be more issues when we have multiple member
pointer types and we clear the cache, but we can leave that for later.

Followup to D118744.
