34a1aff123 Switch out current thread before servicing an interrupt. 
This fixes issues with some system calls (ie.: iSignalSema) writing values directly in the thread's context
but not being picked up because the thread's context was not saved.

3b56af1456 Made breakpoints handling more reliable by moving the breakpoint checking code after function partitioning because a breakpoint inside a non-partitioned function could never be hit. 
Also added a different "first run" check for breakpoints that is only enabled when we come back from paused virtual machine state.
Moved more stuff between "DEBUGGER_INCLUDED" ifdefs.

5fd26ba083 Made address translation take a 32-bits address instead of a 64-bits one. We probably won't ever need to use 64-bits addresses.

c5d4169670 Changed the way the Q and MACflags pipeline is emulated. The current value of the registers are only computed when they are needed instead of tracking the current value at every instruction. Gives a nice FPS boost.
