390721a561 maxwell_3d: Allow texture handles with TIC id zero 
Also remove "enabled" field from Tegra::Texture::FullTextureInfo because
it would become unused.

477d616f7d shader_ir: Unify constant buffer offset values 
Constant buffer values on the shader IR were using different offsets if
the access direct or indirect. cbuf34 has a non-multiplied offset while
cbuf36 does. On shader decoding this commit multiplies it by four on
cbuf34 queries.

9a82dec74a maxwell_3d: Set rt_separate_frag_data to 1 by default 
Commercial games assume that this value is 1 but they never set it. On
the other hand nouveau manually sets this register. On
ConfigureFramebuffers we were asserting for what we are actually
implementing (according to envytools).

c560043581 rasterizer: Drop unused handler. 
This virtual function is called in a very hot spot, and it does nothing.

If this kind of feature is required, please be more specific and add callbacks
in the switch statement within Maxwell3D::WriteReg. There is no point in having
another switch statement within the rasterizer.

fdb199290b GPU/DMA: Partially implemented the 'enable_2d' bit in the DMA engine. 
When not set, this tells the GPU to only use the X size when performing a DMA copy.
This is only implemented for linear->linear and tiled->tiled copies. Conversion copies still retain the assert.

This bit is unset by some games for various purposes, and by nouveau when copying the vertex buffers.

d3ad9469a1 gl_rasterizer: Implement a VAO cache. 
This patch caches VAO objects instead of re-emiting all pointers per draw call.
Configuring this pointers is known as a fast task, but it yields too many GL
calls. So for better performance, just bind the VAO instead of 16 pointers.
