Huw Pascoe a234e4c200 Improved performance of FromAttributeBuffer
Ternary operator is optimized by the compiler
whereas std::min() is meant to return a value.

I've noticed a 5%-10% emulation speed increase.

wwylele 63b6e802cd swrasterizer: remove invalid TODO
This function is called in clipping, before the pespective divide, and is not used in later rasterization. Thus it doesn't need perspective correction.

wwylele 0f35755572 pica/command_processor: build geometry pipeline and run geometry shader
The geometry pipeline manages data transfer between VS, GS and primitive assembler. It has known four modes:
 - no GS mode: sends VS output directly to the primitive assembler (what citra currently does)
 - GS mode 0: sends VS output to GS input registers, and sends GS output to primitive assembler
 - GS mode 1: sends VS output to GS uniform registers, and sends GS output to primitive assembler. It also takes an index from the index buffer at the beginning of each primitive for determine the primitive size.
 - GS mode 2: similar to mode 1, but doesn't take the index and uses a fixed primitive size.
hwtest shows that immediate mode also supports GS (at least for mode 0), so the geometry pipeline gets refactored into its own class for supporting both drawing mode.
In the immediate mode, some games don't set the pipeline registers to a valid value until the first attribute input, so a geometry pipeline reset flag is set in `pipeline.vs_default_attributes_setup.index` trigger, and the actual pipeline reconfigure is triggered in the first attribute input.
In the normal drawing mode with index buffer, the vertex cache is a little bit modified to support the geometry pipeline. Instead of OutputVertex, it now holds AttributeBuffer, which is the input to the geometry pipeline. The AttributeBuffer->OutputVertex conversion is done inside the pipeline vertex handler. The actual hardware vertex cache is believed to be implemented in a similar way (because this is the only way that makes sense).
Both geometry pipeline and GS unit rely on states preservation across drawing call, so they are put into the global state. In the future, the other three vertex shader units should be also placed in the global state, and a scheduler should be implemented on top of the four units. Note that the current gs_unit already allows running VS on it in the future.

wwylele 36981a5aa6 pica/primitive_assembly: Handle winding for GS primitive
hwtest shows that, although GS always emit a group of three vertices as one primitive, it still respects to the topology type, as if the three vertices are input into the primitive assembler independently and sequentially. It is also shown that the winding flag in SETEMIT only takes effect for Shader topology type, which is believed to be the actual difference between List and Shader (hence removed the TODO). However, only Shader topology type is observed in official games when GS is in use, so the other mode seems to be just unintended usage.

wwylele 46c6973d2b pica/shader: extend UnitState for GS
Among four shader units in pica, a special unit can be configured to run both VS and GS program. GSUnitState represents this unit, which extends UnitState (which represents the other three normal units) with extra state for primitive emitting. It uses lots of raw pointers to represent internal structure in order to keep it standard layout type for JIT to access.
This unit doesn't handle triangle winding (inverting) itself; instead, it calls a WindingSetter handler. This will be explained in the following commits
