The final two tests were at fault — expecting POPs to write rather than read. Fixed, so the subset of timing tests as-yet implemented now passes. Which means it's time to slog through further tests.

Rephrased internal operation machine cycles as having only an end. So they're now easy to count. Hence the test machine spots them, and a couple more of the current timing subset passes.

Started trying to wade back to passing tests. Working on the new timing tests first, and focussing on getting the Objective-C test machine to compile bus operations into machine cycles, which means indicating phase to all-RAM delegates.

Reformulated the machine cycle slightly to support posting operation plus phase, thereby exposing the segue points at which waits might be inserted. So: to stick to the rule that CPUs expose the minimum amount of information sufficient completely to reconstruct bus activity. This breaks the Z80 for now.

Started splitting ZX80 and ZX81 paths. Also the '80 fires its horizontal sync a little earlier than the '81, so pulled that back a little.

Implemented a rudimentary way to test that instructions take as long as the FUSE tests think they should. Hence discovered that the (HL)-accessing BIT, RES and SET weren't. Corrected.
