Replaced all references to simulation with emulation
Updated copyright year
Updated .gitignore to reduce chances of random files being uploaded to
the repo
Added .gitattributes to normalize all text files, and to ignore binary
files (which includes the logo and the NEC PDF)
Since the CEN64 core now runs in it's own thread (and doesn't use
the FPU), we can steal the host's FPU state register and not have
to worry about preserving it.
Along with that major overhaul, don't force "extra" features like
simulation statistics and debugging if the user doesn't want them.
Including that code, even when it is not run, mucks with register
allocation or something ever so slightly.
Tell GCC to optimize cold functions for size and stash them away in
a separate part of the binary. Put the simulate core, meanwhile, on
the hot path. Also, bump optimization to -O3 as we can now "afford"
to do so.
Instead of having almost every opcode function load IW off the
stack through the VR4300 pointer, just pass it as an argument on
the stack to reduce binary size and hoist a load up.
Thanks go out to Narann for this idea.
Much of the architecture-specific code uses compiler-agnostic
intrinsics. For this reason, split it out into an arch/ folder,
leaving only the compiler and environment-specific code in os/.
