50657548b1 Make Invalid instruction debug assert a non-debug assert. 
Users need to be able to see this error message. Otherwise they can't
report bugs.

2f9e9bf1fc JIT: completely inline timer reading 
Should be a bit faster on games that heavily use the timer.

a63b9f6713 JIT: remove srawix fallback 
As far as I can tell, this has literally been here since the start of the git
history; maybe it was stubbed out because the author wasn't sure it was right?

It matches the PPC/Broadway manuals perfectly, though.

1ad1a9062a Remove PowerPCState::DebugCount. 
This value was "helpful" for debugging when the stack got corrupted.
Helpful that if gpr[1](Which is the stack pointer with PPC ABI) is zero then the interpreter would spam huge amounts of annoy text saying that we
managed to get in to a "corrupted" state.
This is incremented every instruction on the interpreter, or every block run on the JIT64....Only if debugging is enabled(JIT64 it is a const
variable)
The message is only outputted when interpreter is used and debugging is enabled.

f5c7f676dc Evict registers from the cache based on LRU. 
The old method would always evict the first suitable register, i.e. the
same register every time once the cache got full.  The cache doesn't get
terribly often, but the result is pathological...

816d056657 JIT: implement timer support in mtspr 
Faster, of course, since we avoid the interpreter, but also means we can
get more a more accurate timer in long blocks by adding the offset from the
start of the block to the retrieved timer. I don't know if this will actually
fix any issues, but it's more correct and a nearly-free improvement.

6f617c4175 JIT64: try enabling dcbz again 
This time, check the address carefully beforehand, since apparently some games
do horrible things like running it on non-RAM addresses, or at the very least
virtual addresses.

88095a607a JIT: fix RAM check in load-from-constant-address 
A bug that seems to have been uncovered by allowing immediate-address loads.
Super Monkey Ball 2 crashes without this change -- it's possible, however, that
the game actually requires the MMU hack, since it crashed due to accessing an
address in the 0x20000000-0x3fffffff range.
