GPU: Implemented bits 3 and 1 from the display transfer flags.
Bit 3 is used to specify a raw copy, where no processing is done to the data, seems to behave exactly as a DMA.
Bit 1 is used to specify whether to convert from a tiled format to a linear format or viceversa.

Video core: Fix A4 texture decoding
It was trying to take the LSB from `coarse_x`, which would always be 0
and thus would always return the same texel from each byte. To add
insult to the injury, the conditional was actually the wrong way around
too.
Fixes blocky text in OoT.

Video core: Fix pixelation/blockiness in textures.
This was caused during morton decoding by me not masking the bits of
each coordinate before merging them, so the bits from x could set bits
in y if it was >255.

Pica/VertexShader: Fixed LOOP with more than one iteration.
Previously it wouldn't jump back to the start of the loop code once it reached the end of the block.
Fixes the texture problems in a lot of games.

Pica: Cleanup clipping code and change screenspace z to range from -1..0.
The change in depth range seems to reflect better to what applications are expecting, and makes for cleaner code overall (hence is more likely to reflect hardware behavior).

Asserts: break/crash program, fit to style guide; log.h->assert.h
Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time)
As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing)
Also removed some GEKKO cruft.

GSP: Update framebuffer info on all interrupts
Hardware testing determined that the GSP processes shared memory
framebuffer update info even when no memory transfer or filling GX
commands are used. They are now updated on every interrupt, which isn't
confirmed correct but matches hardware behaviour more closely.
This also reverts the hack introduced in #404 . It made a few games
behave better, but I believe it's incorrect and also breaks other games.
