Log message:
	PR c/4475, c++/3780:
	* c-common.def (SWITCH_STMT): Add SWITCH_TYPE operand.
	* c-common.h (SWITCH_TYPE): Define.
	* c-typeck.c (c_start_case): Set SWITCH_TYPE.
	* stmt.c (all_cases_count): Set lastval to thisval at end of loop.
	Rename spareness variable to sparseness.
	(expand_end_case_type): Renamed from expand_end_case, use orig_type
	if non-NULL instead of TREE_TYPE (orig_index).
	* tree.h (expand_end_case_type): Renamed from expand_end_case.
	(expand_end_case): Define using expand_end_case_type.
	* c-semantics.c (genrtl_switch_stmt): Pass SWITCH_TYPE
	to expand_end_case_type.
	* doc/c-tree.texi (SWITCH_STMT): Document SWITCH_TYPE.
	
	* semantics.c (begin_switch_stmt): Clear SWITCH_TYPE.
	(finish_switch_cond): Set SWITCH_TYPE.
	
	* gcc.dg/Wswitch.c: Fix typos.  Don't return unconditionally
	before all tests.  Move warning one line above to match where it
	C frontend emits.
	* gcc.dg/Wswitch-2.c: New test.
	* g++.dg/warn/Wswitch-1.C: New test.
	* g++.dg/warn/Wswitch-2.C: New test.
