Instead of letting our old copy silently go more and more out-of-sync. In this case, we missed the upstream fix wrt. skipping the declaration of ClassInfos for speculative class types. There are 2 noteworthy functional changes for function `getOrCreateTypeInfoDeclaration()`: 1) The old version always overwrote `torig->vtinfo` with `t->vtinfo` when declaring a new TypeInfo, whereas upstream's `genTypeInfo()` only sets it if it was null before. 2) The old version called `semanticTypeInfo()` during a semantic pass, upstream doesn't. The LDC-specific exception for class types in `builtinTypeInfo()` is still required. Fixes dmd-testsuite's runnable/b16278.d.
