_______________________________________________________
Details:
The second most time consuming function deserves even this kind of manual
optimizations:
- Avoid duplicate coordinate legality check in base_native_pos_to_tile() by
introducing new native_pos_to_index_nocheck() macro
- Rewritten MAP_IS_ISOMETRIC() (compiler SHOULD have been able to do this
already, but now we make sure it happens)
- Avoid moving values between multiple variables (registers in generated
machine code) where one is enough (compiler SHOULD have been able to do this
already, but now we make sure it happens)
