c5284efd4f Rasterizer: Implemented instanced rendering.
We keep track of the current instance and update an uniform in the shaders to let them know which instance they are.

Instanced vertex arrays are not yet implemented.

6030c5ce41 video_core: Eliminate the g_renderer global variable
We move the initialization of the renderer to the core class, while
keeping the creation of it and any other specifics in video_core. This
way we can ensure that the renderer is initialized and doesn't give
unfettered access to the renderer. This also makes dependencies on types
more explicit.

For example, the GPU class doesn't need to depend on the
existence of a renderer, it only needs to care about whether or not it
has a rasterizer, but since it was accessing the global variable, it was
also making the renderer a part of its dependency chain. By adjusting
the interface, we can get rid of this dependency.

d57333406d GPU: Partial implementation of long GPU queries.
Long queries write a 128-bit result value to memory, which consists of a 64 bit query value and a 64 bit timestamp.

In this implementation, only select=Zero of the Crop unit is implemented, this writes the query sequence as a 64 bit value, and a 0u64 value for the timestamp, since we emulate an infinitely fast GPU.

This specific type was hwtested, but more rigorous tests should be performed in the future for the other types.

20d86d8a36 GPU: Partially implemented the Fermi2D surface copy operation.
The hardware allows for some rather complicated operations to be performed on the data during the copy, this is not implemented.
Only same-format same-size raw copies are implemented for now.

f208953585 GPU: Added asserts to our code for handling the QUERY_GET GPU command.
This is based on research from nouveau. Many things are currently unknown and will require hwtests in the future.
This commit also stubs QueryMode::Write2 to do the same as Write. Nouveau code treats them interchangeably, it is currently unknown what the difference is.

9531a29283 GPU: Support multiple enabled vertex arrays.
The vertex arrays will be copied to the stream buffer one after the other, and the attributes will be set using the ARB_vertex_attrib_binding extension.

yuzu now thus requires OpenGL 4.3 or the ARB_vertex_attrib_binding extension.

c3a8ea76f1 ShaderGen: Implemented predicated instruction execution.
Each predicated instruction will be wrapped in an `if (predicate) { instruction_body; }` in the GLSL, where `predicate` is one of the predicate boolean variables previously set by fsetp.

0a5e01b710 ShaderGen: Implemented the fsetp instruction.
Predicate variables are now added to the generated shader code in the form of 'pX' where X is the predicate id.
These predicate variables are initialized to false on shader startup and are set via the fsetp instructions.

TODO:

* Not all the comparison types are implemented.
* Only the single-predicate version is implemented.
