[PATCH] dump CTORs properly wrapped with _Literal with -gimple

[Richard Biener]

This wraps { ... } in _Literal (type) for consumption by the GIMPLE FE.

Bootstrap & regtest ongoing on x86_64-unknown-linux-gnu, will push
to trunk since it eases debugging.

Richard.

        * tree-pretty-print.c (dump_generic_node): Wrap VECTOR_CST
        and CONSTRUCTOR in _Literal (type) with TDF_GIMPLE.
