VM Maker: VMMaker.oscog-eem.2257.mcz

commits-2
 
Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-eem.2257.mcz

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

Name: VMMaker.oscog-eem.2257
Author: eem
Time: 21 July 2017, 11:32:44.600471 am
UUID: 7a3c75a8-72e7-4362-88b7-9a97109592a1
Ancestors: VMMaker.oscog-eem.2256

InterpreterPlugins:
Add the Terf primitives to the HostWindowPlugin as <option: #TerfVM>.  Hence add #TerfVM to namesDefinedAtCompileTime.
Make positive/signedMachineIntegerFor: <inline: #always> since they're merely indirections to 64-bit and 32-bit functions, and with #always we don't bother to generate the method itself.
