Add and pass AllowCXX not only in mergeFunctionTypes but all merge*Type
methods. Use it to determine if reference types should be stripped or
are invalid in mergeTypes. The reason for this is that
mergeFunctionTypes allows CXX functions with exception specifiers but
crashes on reference types (in the return or argument position). This is
going to be used by D88384 <https://reviews.llvm.org/D88384>.
