Michel Heily a47cb18cda core/arm7tdmi/arm/: Fix wrong calculation of op1 in DATA_PROCESSING instruction when RN==R15 
The docs state: "If a register is used to specify the shift amount the PC will be 12 bytes ahead"
I probably misread that when implementing DataProcessing instructions,
and because of that added 4 bytes to (op1+8) when shift amount was specified by a rotated immediate.

Fixes #6 (and probably tons of other bugs too!)

Michel Heily c6feb5d500 core: Optimizing GameBoyAdvance::frame 
Profiling GameBoyAdvance::frame shows that it spends way too much time idleing
on SoundController::update & Gpu::step waiting for the cycle count to
reach to the next event, Consuming cpu time for the Arm7tdmi core.

This commit changes the implementation of the main loop functions so
that the CPU will run as many cycles as possible and the peripherals
will only be updated when needed.
The is a performance improvement of roughly 50% in fps in some games!
