The very bare beginnings of the Mist-Classes package.
Many little changes. Most are connected with getting call and return to work, and handling args and temps of methods correctly with call and return.
In the midst of changes to the assignment of variables to locations. Work in progress, currently broken. Partially done updating tests for the new call/return world. Added handling of group 2 and group 5 instructions to the disassembler.
More steps towards sane location assignment in Fog. Not quite there yet; still broken.
Further rework of location assignment. Most things seem to be working now, but there's still a failure in the echoMany test. Updated remaining tests to be methods that return rather than programs. Updated disassembler tests to account for minor differences due to location assignment changes.
Fix merge conflicts due to not pulling before committing.
Fixed the bug in loop code generation that was causing the echoMany test to fail.

Expanded the comment about how locations are assigned.

Updated the echoMany test to expect the machine code generated in the new world of Method nodes.
Updated baseline for Pharo 3.0. The 3.0 AsmJit contains my fixes and is in the base image, so no longer needs to be specified. Now have to specify loading OSProcess in order to get tests to work. Disassembler tests were trying to remove executable files that they never created, which caused an error in Pharo 3.0.
