c++: Treat OPAQUE_TYPE types as an aggregate type [PR97947]
MODE_OPAQUE and the associated OPAQUE_TYPE were added to stop the optimizers
from knowing how the bits in a variable with an opaque type are laid out.
This makes them a kind of pseudo aggregate type and we need to treat them
as such when we process the INIT initializer for variables with an
opaque type.
