[ARM] Implement cmpl
[ARM] dcbst implementation.
[ARM] Missed flushing our register caches in mtmsr. This would cause a buttload of problems, including the suspected ori being wrong issue. So flush caches and reenable ori.
Core: Remove dead code

We never call SetState with CORE_UNINITIALIZED, and always call
Core::Stop() directly.
[ARM] Remove Fastmem. It is buggy and may never have the potential to work correctly.
[ARM] Add support for IMMs to the GPR reg cache. Not yet using it since it doesn't quite work
[ARM] Make sure to flush a register location. IMM still doesn't work...
NetPlay: Remove some dead code
NetPlay: Split the server out, and make the local system manage a client as well

This should be transparent, but it may cause regressions.

The idea here is that now all players, including the host of the server,
talk to the server through TCP/IP networking. This significantly reduces
our codepaths through netplay, and will prevent strange local-only bugs
from happening.

The cleanup isn't 100% finished yet. The NetPlay dialog still drives the
server through private APIs. I eventually want to sanction off the server
entirely, so all communication is done through TCP/IP. This will allow us
to have high-traffic public servers that can relay multiple games and
lobbies at a time, and split off channel and game management to people
other than the host.

This is all still just a pipe dream, though.
NetPlay: Remove the base NetPlay class

It's only used by the NetPlayClient. For now, keep around NetPlay.cpp,
but we'll remove that soon.
NetPlay: Remove NetPlay.h / NetPlay.cpp

Now the server and client implementations are entirely separate.
NetPlay: Supply every player's ping data to the client

This means that we now have feature parity with the combined server
before.
NetPlayServer: Close the socket when we're done with it

This would allow a new socket to be created with the same port after
we close it. However, we can't reuse it immediately because of the TCP
TIME-WAIT state.
Merge branch 'netplay'
[ARM] Fix IMM support in the register cache.
[ARM] Some initial support for immediates in integer. Plenty more to go.
