* expr.h (emit_storent_insn, expand_expr_real_1,
	expand_expr_real_2): Declare.
	* expr.c (emit_storent_insn, expand_expr_real_1,
	expand_expr_real_2): Export.
	(store_expr): Setting and evaluating dont_return_target is
	useless.
	(expand_expr_real_1, <case GOTO_EXPR, RETURN_EXPR, SWITCH_EXPR,
	LABEL_EXPR and ASM_EXPR>): Move to gcc_unreachable.
	* except.c (expand_resx_expr): Rename to ...
	(expand_resx_stmt): ... this.  Rewrite to take gimple statement.
	* except.h (expand_resx_stmt): Declare.
	* stmt.c: Add include gimple.h
	(expand_asm_expr): Rename to ...
	(expand_asm_stmt): ... this. Rewrite to take gimple statement.
	(expand_case): Rewrite to take gimple statement.
	* tree.h (expand_asm_stmt): Declare.
	(expand_case): Change prototype.
	* Makefile.in (stmt.o): Depend on gimple.h.
	* builtins.c (expand_builtin_synchronize): Build gimple asm
	statement, not an ASM_EXPR.
	* cfgexpand.c (gimple_cond_pred_to_tree, set_expr_location_r,
	gimple_to_tree, release_stmt_tree): Remove.
	(expand_gimple_cond): Don't call gimple_cond_pred_to_tree or
	ggc_free, but hold comparison code and operands separately.
	Call jumpif_1 and jumpifnot_1 instead of jumpif and jumpifnot.
	(expand_call_stmt, expand_gimple_stmt_1,
	expand_gimple_stmt): New helpers.
	(expand_gimple_tailcall): Don't call gimple_to_tree, expand_expr_stmt,
	release_stmt_tree.  Call expand_gimple_stmt instead.
	(expand_gimple_basic_block): Ditto.

	* calls.c (emit_call_1): Don't look at EH regions here, make
	fntree parameter useless.
	(expand_call): New local rettype for TREE_TYPE(exp), use it
	throughout.  Remove local p, use addr instead.
	Don't look at EH regions here.
