[PATCH][GIMPLE FE] Dump anon SSA names w/o identifier

[Richard Biener]

The parser only groks those in declarations so make it easy and
emit them that way with -gimple.

Tested on x86_64-unknown-linux-gnu.

        * tree-pretty-print.c (dump_generic_node): For -gimple dump
        anonymous SSA names without identifier.
