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.
