Now that we are able to compact map space, we can also get rid of the
map space and allocate maps in the old space instead. This CL introduces
a FLAG_map_space for enabling/disabling the map space but the map space
remains enabled by default for now.
Without a separate space for maps, the GC can't prevent relocation of
maps anymore. Therefore this CL always allows compaction of maps when
running without a map space. Rename flag to --compact-maps to better fit
this scenario.
mkgrokdump and debug_helper also need to be updated to look for maps
also in the old space. The map space is now optional.

After https://crrev.com/c/3416191 there are too many mixed concerns in
the clusterfuzz directory. We split it into js-fuzzer, foozzie and
trials.
