Add extra check for llvm::Any::TypeId visibility

This check should ensure we don't reproduce the problem fixed by
02df443d

More accurately, it checks every llvm::Any::TypeId symbol in libLLVM-x.so and
make sure they have weak linkage and are not local to the library, which would
lead to duplicate definition if another weak version of the symbol is defined in
another linked library.
