Rename "alloc bit" to "valid object bit" (VO bit) in code and scripts.
The constant `COORDINATOR_ONLY_STW` is deprecated and has no effect.
This is an alternative approach for #218 that addresses the upstream API change in mmtk/mmtk-core#817.  This PR simply saves the mutator pointers into a `VecDeque` and embeds it into the iterator.
That will show the actual used cargo version specified by
`rust-toolchain`.
We currently allow build with a fixed plan to work with the current performance CI. mmtk/mmtk-core#901 attempts to add more plans to our performance CI. This PR adds some missing features for genimmix and stickyimmix. 

We do not need those plans once we move to the new `running-ng` scripts.
* Pass hotspot cmdline flags to mmtk

* lower hotspot flag priority

* Remove println

* Use typed setter

* Update mmtk-core
We load/store edges using ptr::{read,write}_unaligned on x86 and x86_64
to workaround unaligned edges in code roots.
