Fix detection of special reference variables

Browse source 
D2.072 apparently doesn't set the STCforeach storage class for each
special reference anymore. So let's consider all references which aren't
parameters, i.e., all locals with STCref, as special references.

By-ref parameters are different as we simply use the LL pointer parameter as
lvalue for the variable, no extra alloca required. Special references are
automatically dereferenced pointers and as such occupy a dedicated alloca for
the address.
