    c++: default ctor that's also a list ctor [PR102050]

    In grok_special_member_properties we need to set TYPE_HAS_COPY_CTOR,
    TYPE_HAS_DEFAULT_CONSTRUCTOR and TYPE_HAS_LIST_CTOR independently
    from each other because a constructor can be both a default and list
    constructor (as in the first testcase), or both a default and copy
    constructor (as in the second testcase).

            PR c++/102050

    gcc/cp/ChangeLog:

            * decl.c (grok_special_member_properties): Set
            TYPE_HAS_COPY_CTOR, TYPE_HAS_DEFAULT_CONSTRUCTOR
            and TYPE_HAS_LIST_CTOR independently from each other.

    gcc/testsuite/ChangeLog:
