Emulator Hangs after Cycle Count Rollover

[mesheets]

The emulator hangs after the 32-bit cycle counter rolls over.

Cycle counter is used somewhat widely throughout the emulator, so updating to handle rollover appears to be non-trivial.

An interim step is to increase the cycle counter size from a 32-bit signed integer to a 64-bit signed integer (long long).

Changes to support mitigation of this hang are in the branch cycle-count-typedef. Given the scope of change, reverse integration is pending outcome of the monitoring of the changes on that branch.
