[PATCH] Remove dead function_ann and static_var_ann


All unused.  Bootstrapped and tested on x86_64-unknown-linux-gnu, applied
to trunk.

Richard.

2009-04-27  Richard Guenther  <rguenther@suse.de>

	* tree-flow-inline.h (function_ann): Remove.
	(get_function_ann): Likewise.
	* tree-dfa.c (create_function_ann): Remove.
	* tree-flow.h (struct static_var_ann_d): Remove.
	(struct function_ann_d): Likewise.
	(union tree_ann_d): Remove fdecl member.
	(function_ann_t): Remove.
	(function_ann, get_function_ann, create_function_ann): Remove
	declarations.
