In theory, the Z80 core should work on 32-bit builds now; however, I suspect there is some code that cannot deal with most of the Z80 registers not having a native register so more work will be needed

Fix flags for rra, rrca, rla and rlca. Fix timing for rr, rrc, rl and rlc when using IX or IY. Fix access to I and R registers (R still needs to be made 7-bit though). Fix flags for ld a, i. The fix for access to I fixes PCM playback in Titan Overdrive and music playback in Crackdown.

The local clone on my laptop got messed up and some changes had not been pushed. This commit represents the status of the working copy from that clone. It unfortunately contains some changes that I did not intend to commit yet, but this seems like the best option at the moment.

Fix handling of code writes for Z80 core. This seems to get things close to being back to where they were before the big refactor that broke the Z80 core. Some problems remain. Notably the sound driver in Sonic 2 is still quite broken.
