Michel Heily c4c8163b0e optimize/timers: Get rid of the while loop in Timer::update. 
Profiling with 'perf' I discovered that too much time was spent inside
Timer::update when the prescalar was 0 (frequency of 1 cycle).
This was due to the while loop I used. I optimized this loop out and
there is an appearent performance increase.

Michel Heily f0aa671674 optimize/cpu: Pass Arm/Thumb Instruction and other large structs as references. 
Also, get rid of unnecessary derive Copy.

Since the ArmInstruction (and Thumb) derived from Copy, the compiler
always saves them to the stack when they are passed by value to other
functions, thus making some unwanted performance overhead.

I removed the derive Copy, and also pass them as references. This
project has a lot of "derive Copy" everywhere, and I should take note if
this is happenning elsewhere aswell.

Michel Heily d9ce1c7d8d optimize/arm: Improve arm instruction condition check. 
Obviously AL(always) instructions are the most common, so prioritize checking these first.

Michel Heily c68b9502fe bugfix: Fix bad write impl of DISPSTAT again. 
I should really pay more attention to the docs..
The previous fix (bb843ea5) was not enough as it caused vblank,hblank
and vcount-match flags to be overwritten when they really should have
just been ignored.

This caused Dragon Ball - Advance Adevnture to fail booting

Michel Heily c96fa38a2d bugfix: Fix improper write to DISPSTAT register 
For some reason, probably typing mistkae, I `or`ed the value being written to DISPSTAT,
causing bits to never actually turn off, affectivly making HBLANK/VBLANK
interrupts linger forever.

This probably has caused some nasty glitches that I don't even know of, but two confirm issues solved
by this are Mariokart and Pacman.

This commit fixes #14 and #13

This commit yeilds yet another 5% performance improvment.

The next step is to move `advance_pc` into the instructions themselves
and save the `match result` per executed instruction

Michel Heily 1f79205f51 optimize: CPU Pipeline optimization part 1 
In preperation for later optimization in the CPU pipeline
implementation, this commit refactors the arm/thumb exec functions to return a
CpuAction (Whether to advance the program counter or to flush the
pipeline)

Currently, a lot of host cycles are wasted in the arm7tdmi pipeline
Refill1 & Refill2 states. Optimizing these steps out would make the CPU
a bit faster.
