tree.h (SSA_VAR_P): Simplify.

Browse Source 
2012-08-09  Richard Guenther  <rguenther@suse.de>

	* tree.h (SSA_VAR_P): Simplify.
	* tree-ssanames.c (make_ssa_name_fn): Strengthen assert.
	* fold-const.c (fold_comparison): Check for default def first
	before checking for PARM_DECL.
	* tree-complex.c (get_component_ssa_name): Likewise.
	* tree-inline.c (remap_ssa_name): Likewise.
	* tree-ssa-loop-ivopts.c (parm_decl_cost): Likewise.
	* tree-ssa-structalias.c (get_fi_for_callee): Likewise.
	(find_what_p_points_to): Likewise.
	* tree-ssa-operands.c (add_stmt_operand): Simplify.
