This allows us to not have to specify -opaque-pointers when updating
IR tests from typed pointers to opaque pointers.

We detect opaque pointers in .ll files by either looking for relevant tokens.

We lazily set LLVMContextImpl::OpaquePointers unless
-opaque-pointers[=0] is explicitly specified. We lazily set it based on
the first type of pointer created, whether opaque or typed.
