AiFloodMovementAndRange loop issue.

[Huichelaar]

The new AiFloodMovementAndRange seems to call AddMap with the unit's X and Y pos, instead of the X and Y iterated on in the loop:

C-SkillSys:

fe8u-cskillsys/Wizardry/Core/WeaponRange/Source/MiscHooks.c

Line 161 in c4fb618

AddMap(unit->xPos, unit->yPos, mask);

Decomp:
https://github.com/FireEmblemUniverse/fireemblem8u/blob/master/src/cp_battle.c#L263

As a result, the RangeMap does not get properly filled. This can cause the issue where units with AI2 = 0x6 do not move to targets within 2*mov. There's a discussion with someone who ran into this problem in the FEU discord:

Suggested solution: use ix and iy instead of unit->xPos and unit->yPos.
