[PATCH] passes.c: handle register_pass with a name starting with a star

["Dennis, CHENG Renquan" <crquan@fedoraproject.org>]

The gcc included passes have the feature that a name starting with a start do
not dump anything; so should the plugin registered passes have.

And since passes from gcc and from plugin both have been asserted having a name
at least; the check for pass->name in any following code is not necessary.

Bootstraped and tested on i686-pc-linux-gnu with "--enable-checking=all".

2010-07-10  "Dennis, CHENG Renquan" <crquan@fedoraproject.org>

	* passes.c (register_pass): handle plugin registered passes with
	a name starting with a star do not dump anything.
	* passes.c: remove some cases of pass->name check.

---
Updated: "enum tree_dump_index tdi" should be put inside the block.
