    c++: unroll pragma in templates [PR111529]

    We were failing to handle ANNOTATE_EXPR in tsubst_copy_and_build, leading
to
    problems with substitution of any wrapped expressions.

    Let's also not tell users that lambda templates are available in C++14.

            PR c++/111529

    gcc/cp/ChangeLog:

            * parser.cc (cp_parser_lambda_declarator_opt): Don't suggest
            -std=c++14 for lambda templates.
            * pt.cc (tsubst_expr): Move ANNOTATE_EXPR handling...
            (tsubst_copy_and_build): ...here.

    gcc/testsuite/ChangeLog:

            * g++.dg/ext/unroll-4.C: New test.
