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.
Start working in a "extra" mode for debugging and other features
that we don't want on the main path. As a demonstration of what we
can do with this extra mode, print out a bunch of simulation info
that can help us optimize offline.
If we place larger, less commonly used structures after our
frequently accessed state variables, the average size of x86
instructions will be reduced due to the smaller offsets off
the base pointer.
