VM Maker: Cog-eem.344.mcz

commits-2
 
Eliot Miranda uploaded a new version of Cog to project VM Maker:
http://source.squeak.org/VMMaker/Cog-eem.344.mcz

==================== Summary ====================

Name: Cog-eem.344
Author: eem
Time: 29 June 2017, 4:44:41.921001 pm
UUID: 57f1233e-14ba-4fa9-a5da-818ec53d837c
Ancestors: Cog-eem.343

Move SimulatorHarness into VMMaker.  It is useful in tests.
Fix Spur32BitPreen>>reportSizes given the changes to total heap size in VMMaker.oscog-eem.2237 & VMMaker.oscog-eem.2244.
