runtime: set minimum heap size to 4Mbytes

Set the minimum heap size to 4Mbytes except when the hash
table code wants to force a GC. In an unrelated change when a
mutator is asked to assist the GC by marking pointer workbufs
it will keep working until the requested number of pointers
are processed even if it means asking for additional workbufs.
