Use more switch statements.
2019-09-24 Martin Liska <mliska@suse.cz>
* cfgexpand.c (gimple_assign_rhs_to_tree): Use switch statement
instead of if-elseif-elseif-...
* gimple-expr.c (extract_ops_from_tree): Likewise.
* gimple.c (get_gimple_rhs_num_ops): Likewise.
* tree-ssa-forwprop.c (rhs_to_tree): Likewise.
