When 66b992c fixed https://bugs.dolphin-emu.org/issues/12133,
it did so by removing the broken address calculation entirely and
always using the slow path. This caused a performance regression,
https://bugs.dolphin-emu.org/issues/12477.
This commit instead replaces the broken address calculation with
a BAT lookup. If the BAT lookup succeeds, we can use the old fast
path. Otherwise we use the slow path.
Intends to improve https://bugs.dolphin-emu.org/issues/12477.
