fa32f751d3 ShaderGen: Handle ShaderCode objects directly. 
ShaderGeneratorInterface does not have virtual function members, so we have to implement each type explicitly.

c211450b99 OGL: implement bounding box support with ssbo 
This implemention tries to be as accurate as the old SW implemention, but it will remove the dependcy of our vertexloader on videosw.

6d4867e36a Fixes missing objects on Adreno hardware. 
This particular bug from our friends over at Qualcomm manifests itself due to our alpha testing code having a conditional if statement in it.
This is a fairly recent breakage this time around, it was introduced in the v95 driver which comes with Android 5.0 on the Nexus 5.

So to break this issue down; In our alpha testing code we have two comparisons that happen and if they are true we will continue rendering, but if
they aren't true we do an early discard and return. This is summed up with a fairly simple if statement.

if (!(condition_1 <logic op> condition_2)) { /* discard and return */ }

This particular issue isn't actually due to the conditions within the if statement, but the negation of the result. This is the particular issue that
causes Qualcomm to fall flat on its face while doing so.

I've got two simple test cases that demonstrate this.
Non-working: http://hastebin.com/evugohixov.avrasm
Working: http://hastebin.com/afimesuwen.avrasm

As one can see, the disassembled output between the two shaders is different even though in reality it should have the same visual result.

I'm currently writing up a simple test program for Qualcomm to enjoy, since they will be asking for one when I tell them about the bug.
It will be tracked in our video driver failure spreadsheet along with the others.

bc9ef95643 Support Sampler binding in the shader. 
In the cases where we support the binding layout keyword, use it for more than binding UBO location.
This changes it so it is supported for samplers as well.

Instances when this is enabled is if a device supports GL_ARB_shading_language_420pack, or if it supports GLES 3.10.

52c42a2946 VideoCommon: fix indirect texture coordinate computation in TEV. 
Even if an indirect texture stage doesn't actually sample a texture, we
still need to emit the relevant math.

068f26d2aa PixelShaderGen: Fix an issue with color combiner compare mode and simplify the affected line a bit. 
This was a mistake of mine when translating floating point values to integer values.
Also, the max() part of that line was just completely redundant because the sign of an absolute value is always greater than or equal to zero.

Fixes issue 7178.

3251d78f89 Add initial support for GLSL ES 3.10. 
GLSL ES 3.10 adds implicit support for the binding layout qualifier that we use.
Changes our GLSL version enums to bit values so we can check for both ES versions easily.
