Currrently the size of the array reg_is_wrapped_separately is LAST_SAVED_REGNUM.
But LAST_SAVED_REGNUM could be regno that is being saved. So the size needs
to be `LAST_SAVED_REGNUM + 1` like aarch64_frame->reg_offset is.

Committed as obvious after a bootstrap/test for aarch64-linux-gnu.

gcc/ChangeLog:

	* config/aarch64/aarch64.h (machine_function): Fix the size
	of reg_is_wrapped_separately.
