	assert SWITCH_BODY is non-NULL.
	* tree-pretty-print.c (dump_generic_node): Remove SWITCH_LABELS
	handling.
	* tree.c (block_may_fallthru): Always return true; for SWITCH_EXPR.
c/
	* c-typeck.c (c_start_case): Build SWITCH_EXPR using build2 instead
	of build3.

ada/
	* gcc-interface/trans.c (Case_Statement_to_gnu): Build SWITCH_EXPR
	using build2 instead of build3.
jit/
	* jit-playback.c (add_switch): Build SWITCH_EXPR using build2 instead
	of build3.  Formatting fixes.  Adjust funciton comment.
fortran/
	* trans-decl.c (gfc_trans_entry_master_switch): Build SWITCH_EXPR
	using fold_build2_loc instead of fold_build3_loc.
