move address translation cache fields from global variables to the m68k struct, as
...
this way we can pass around one pointer and access them all in the future.
This happens to win 5-10% performance, because now the code generator can generate a single
global variable pointer to get to all of the translation cache/range fields at once.

pull the PC masking into the code translation cache, so that we only need to mask the PC on our slow path. Gives us another 5-10% speedup.

Created address translation fast path for code reads, separated slow path into separate function so the fast path is more likely to be inlined. 10-20% performance improvement

Mapped memory ranges should always be given preference, since they can't actually cause a bus error or affect any read/write operations over the 68k bus.
