Updates for sail-arm release
We want to ensure that no_devices.sail and devices.sail have the same
effect footprint, because with a snapshot-type release in sail-arm, we
can't rebuild the spec with asl_to_sail every time we switch from
running elf binaries to booting OS's. This commit allows registers to
have arbitrary effects, so registers that are really representing
memory-mapped devices don't have to have the wmem/rmem effect.
