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

Name: VMMaker.oscog-eem.2556
Author: eem

UUID: 4981a174-0196-4d71-8937-a69b4c271462
Ancestors: VMMaker.oscog-eem.2555

Make primitiveDoMixedArithmetic persist in the image header as bit 6 of the flags.
Make it g/settable via Smalltalk vmParameterAt: 48.
Nicolas, I'll leave it up to you whether you want to keep parameter 75 as an alternative way of setting it.
