4717e94fa3 remove value buddies after setting sites to junction sites, not after populating junction sites
This mirrors how snapshots are captured and restored for branch events.
Also, switch back to resolving junction sites before capturing fork
snapshots so we capture the true state of each value immediately before
the branch.

8b2a6f85fc remove divideCR and remainderCR
This forces the compiler to explicitly move the constant operand into
a register, avoiding the possibility that AX or DX might be unavailable
when the assembler needs them.
