[arm][aarch64] Make no_insn issue to nothing
no_insn is documented as:
an insn which does not represent an instruction in the final output,
thus having no impact on scheduling.
and is used in that way by the arm port (e.g. for define_insns that
expand to comments). However, most scheduling descriptions instead
assigned units to no_insn patterns, in some cases treating them as more
expensive than a plain move.
This patch removes the no_insn handling from individual scheduling
descriptions and uses a common define_insn_reservation for all CPUs.
