Core: Move FPSCR exception flags to a typed enum
JIT: add basic register allocation heuristics

Should be at least a bit better than the previous LRU approach. Currently
has two basic components: whether a register is dirty (dirty registers need
to be stored, so clobbering them hurts more) and how many other registers will
be used between now and the next time a register gets used.

Also don't pre-load values that don't need to be in registers.
Reimplement Bounding Box calculation using the software renderer.
Fix linux build and various warnings.

Increase savestate version.
Get buildbot to compile.
Several small optimizations.
Fixed a small bug.
Fix compile errors after rebase.
Removed the MMU Speed Hack option. The TLBHack is now enabled if the MMU option is disabled.  This will help catch cases where a game requires the TLBHack but the option has not been set in the game ini.  It also removes the possibility to mistakenly enable both the MMU and TLBHack.
Added some of the MMU registers into the debugger Register window
VolumeCreator: Make master key arrays static

Only used within this translation unit.
ControllerEmu: Get rid of redundant string appending

Changed Dump Frames References
Add AArch64 JIT recompiler to wxWidgets UI.

This also fixes an issue where it would show the ARMv7 JIT recompiler on AArch64, also the issue of showing the now non-existant ARM JITIL.
Also fixes an issue where it would show the x86 JIT recompilers on a non ARM platform.
Move bDumpFrames to SConfig (and it's references)
Software: Remove obsoleted VideoConfigDialog.
TASInputDlg: Fix some potential uninitialized variable warnings.

Also guard against null (even if it doesn't happen it stops more warnings if someone compiles with -Wall or runs analysis with clang.
