cmd/compile: pass types on SSA Store/Move/Zero ops
For SSA Store/Move/Zero ops, attach the type of the value being stored to the op as the Aux field. This type will be used for write barrier insertion (in a followup CL). Since SSA passes do not accurately propagate types of values (because of type casting), we can't simply use type of the store's arguments for write barrier insertion. Passes "toolstash -cmp" on std. Updates #17583.
