    coroutines: Fix cases where proxy variables are used [PR94879]

    There are several places where the handling of a variable
    declaration depends on whether it corresponds to a compiler
    temporary, or to some other entity.  We were testing that var
    decls were artificial in determining this.  However, proxy vars
    are also artificial so that this is not sufficient.  The solution
    is to exclude variables with a DECL_VALUE_EXPR as well, since
    the value variable will not be a temporary.
