* gcc/tree-pass.h: Added comment about not dumping passes with name
starting with star in struct opt_pass.
* gcc/passes.c (register_dump_files_1): Don't do dump for a pass with
name starting with star.
* gcc/doc/passes.texi (Pass manager): Mention pass names and special
meaning of star prefix to avoid dump.
