JIT: use fastmem loads in MMU mode.

Even in games that require MMU mode, loads outside the area specified by
the BAT are rare, so fastmem is a substantial improvement.

All of the interesting changes are in the backpatch handler, to make it
generate DSI exceptions correctly.
JIT: simplify code using MOVTwo.

D3D+OGL: choose blendenable over logicopenable.

No sane game should turn on both logicopenable and blendenable in the same
blend mode, but not every game is sane. Fixes issue 6009.

Fix many bugs with the Symbols menu (when run with -d argument).
The Symbols menu is now fully useable.
Add "Load bad map file" option for map files on disc that don't quite match.
Currently it is very simple and naive, but filters out most of the bad matches.
Convert spaces to tabs in IDA Pro script.
Apparently c_str doesn't return a C str.
Merge bad map file loading into the original function.
Load 4 column map files like in American Mensa Academy.
Unfortunately the map files in American Mensa Academy don't correspond to the release version.
But at least now if other games use those map files we will be able to load them.
Remove white space at ends of lines.
Rename menu items, stop using PanicAlertT, remove -d when running from visual studio.
I accidentally committed my addition of the -d option that I used for testing, now it's fixed.
