    c++: NRV and ref-extended temps [PR101442]

    This issue goes back to r83221, where the cleanup for extended ref temps
    changed from being unconditional to being tied to the declaration they
    formed part of the initializer for.

    The named return value optimization changes the cleanup for the NRV
variable
    to only run on the EH path; we don't want that change to affect tempora=
ry
    cleanups.  The perform_member_init change isn't necessary (there 'decl'=
 is
a
    COMPONENT_REF), it's just for consistency.

            PR c++/101442

    gcc/cp/ChangeLog:

            * decl.c (cp_finish_decl): Don't pass decl to push_cleanup.
            * init.c (perform_member_init): Likewise.
            * semantics.c (push_cleanup): Adjust comment.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/initlist-nrv1.C: New test.=
