Vincent Duvert 8bb459aae5 VideoCommon: Fix GetInterpolationQualifier calls
Commit 4969415 modified calls to GetInterpolationQualifier, but mistakenly changed the order of some boolean parameters: GetInterpolationQualifier(true, false) was changed to GetInterpolationQualifier(…, false, true).

Should fix #9783.

Jules Blok debaf63fe8 VertexShaderGen: Move the sonic epsilon hack to the vertex shader.
In the vertex shader we have control over the depth clipping planes,
so we don't have to offset every floating point value and lose accuracy.

Jules Blok a141e91dd2 OGL: Check for GL_DEPTH_CLAMP support.
It's not available in OpenGL ES and officially it's not supported on OpenGL 3.0/3.1.

Fallback to old depth range code if there is no method to disable depth clipping.
It's more important to have correct clipping than to have accurate depth values.
Inaccurate depth values can be fixed by slow depth.

Scott Mansell 1a831cfc7d Multithreadded Shadergen: Second Pass over vertex/lighting Shadergens
As much as possible, the asserts have been moved out of the GetUID
function. But there are some places where asserts depend on variables
that aren't stored in the shader UID.

Scott Mansell 4969415f38 Remove global refrences from common code.
Bug Fix: Previously vertex shaders and geometery shaders didn't track
         antialaising state in their UIDs, which could cause AA bugs
	 on directx.

Scott Mansell 53c402dbc5 Multithreadded Shadergen: First Pass over vertex/lighting Shadergens
The only code which touches xfmem is code which writes directly into
uid_data.

All the rest now read their parameters out of uid_data.

I also simplified the lighting code so it always generated seperate
codepaths for alpha and color channels instead of trying to combine
them on the off-chance that the same equation works for all 4 channels.

As modern (post 2008) GPUs generally don't calcualte all 4 channels
in a single vector, this optimisation is pointless. The shader compiler
will undo it during the GLSL/HLSL to IR step.

Bug Fix: The about optimisation was also broken, applying the color light
         equation to the alpha light channel instead of the alpha light
	 euqation. But doesn't look like anything trigged this bug.

Stenzek e6b2212ec0 ShaderGen: Only specify storage qualifier in interface block when needed
Drivers that don't support GL_ARB_shading_language_420pack require that
the storage qualifier be specified even when inside an interface block.

AMD's driver throws a compile error when "centroid in/out" is used within
an interface block.

Our previous behavior was to include the storage qualifier regardless, but
this wasn't working on AMD, therefore we should check for the presence of
the extension and include based on this, instead.

Ryan Houdek 3ab7806e24 Workaround OS X video driver bug #24983074
OS X's shader compiler has a bug with interface blocks where interface block members don't properly inherit the layout qualifier from the interface
block.
Work around this limitation by explicitly stating the layout qualifier on both the interface block and every single member inside of that block.

Ryan Houdek a8c37e5d6b Remove two more asserts in VertexShaderGen.
As confirmed by a hardware test if we are using the texgen type of COLOR_STRGBC0/STRGBC1 then it sets the texture coordinates to those values
regardless of what the input form or source row is.

Thanks to Ornox for testing again

Ryan Houdek 92e9382e61 Confirm with hardware test that the high bit of the input form is ignored.

Ryan Houdek e1d36f91fc Fix a few asserts in the VertexShaderGen.
Removes a couple asserts in the vertex shader gen when dealing with the input form.
Typically input form ABC1 is used, so it'll pull in the first three elements and always set the fourth to 1.0
The other input form available is AB11, which sets the last two components to 1.0 (Theoretically).
No titles actually use this input form that we know of except for Project M, but it can have some fairly drastic visual differences.

Confirmed correct by hardware test

Jules Blok 9805f70913 VideoConfig: Replace FastDepthCalc by ForcedSlowDepth.
Fast depth is now more accurate than slow depth and should always be used.
The option will be kept in a different form as it is still used as a hack to fix some games.
Also, the slow depth code path will still be relied upon by cards that don't support GL_ARB_clip_control.

Stenzek 617f9d9532 ShaderGen: Remove virtual methods from ShaderGeneratorInterface, move string buffer to ShaderCode
This fixes the crashes occuring at startup with a non-empty shader cache.
Because LinearDiskCache reads/writes to the storage of ShaderUid, ShaderUid must be trivially copyable.
Additionally, adds a static assert to LinearDiskCache to ensure this doesn't happen in the future.

The initialization of ShaderUid data has been moved to the code generation functions, so the above condition holds true.
