Follow up on CL 122665.

We now do the two-step memory protection strategy (first protect the
from space with PROT_READ and later protect it with PROT_NONE) only if
the from space is a rosalloc space (excluding the more common bump
pointer space case). This strengthens the GC verification for the bump
pointer space case as we avoid the case where mutators run while the
from space is PROT_READ rather than PROT_NONE.

Add a command line flag to override the minimum interval for the
hspace compaction for OOM and set it to zero in the gcstress/gcverify
run-tests to run the hspace compaction more frequently in tests.

Fix some comments.
