This completes the propagation of type IDs through bitcode reading, and switches remaining uses of getPointerElementType() to use contained type IDs. The main new thing here is that sometimes we need to create a type ID for a type that was not explicitly encoded in bitcode (or we don't know its ID at the current point). For such types we create a "virtual" type ID, which is cached based on the type and the contained type IDs. Luckily, we generally only need zero or one contained type IDs, and in the one case where we need two, we can get away with not including it in the cache key. With this change, we pass the entirety of llvm-test-suite at O3 with opaque pointers. Differential Revision: https://reviews.llvm.org/D120471
