[lto][patch] remove more unused code

[Rafael Espindola <espindola at google dot com>]

Namespaces don't survive the reset_land_decl_specifics. This patch
removes support for them in the streamer.

2009-01-21  Rafael Avila de Espindola  <espindola@google.com>

	* lto-function-in.c (input_namespace_decl): Remove.
	(input_tree_operand): Don't call input_namespace_decl.
	* lto-function-out.c (output_namespace_decl): Remove.
	(output_tree): Don't call output_namespace_decl.

Cheers,
