d54ca2a16a PixelShaderGen: Don't include host early z support in UID 
Disable it at shader generation time instead. This way the UIDs are
sharable.

35caf48d7d Add a workaround for a PowerVR glsl compiler bug 
It seems it doesn't like negating arguments for bitops, so suff like
"var <<= (-othervar);"
fails to compile

da43f9a156 PixelShaderGen: Always divide the texture coordinates by q. 
Some games will set q to a different value than 1.0 through
texture matrix manipulations. It seems the console will still
do the division in that case.

24e5d21780 Multithreadded Shadergen: Second pass over Pixel Shadergen. 
Note: It's not 100% perfect, as some of the GPU capablities leak into the
pixel shader UID.

Currently our UIDs don't get exported, so there is no issue. But someone
might want to fix this in the future.

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.

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.

0d996f512b Multithreadded Shadergen: First pass over pixel Shadergen 
Bug Fix: It was theoretically possible for a shader with depth writes
         disabled to map to the same UID as a shader with late depth
	 writes.
	 No known test cases trigger this.

e99364c7c9 UID Change: Fix bug with indirect stage UIDs 
Bug Fix: The normal stage UIDs were randomly overwriting indirect
         stage texture map UID fields. It was possible for multiple
	 shaders with diffrent indirect texture targets to map to
	 the same UID.
         Once again, it dpesn't look like this bug was ever triggered.

03f2c9648d Shader UID change: Only store the two bits of components we need. 
This frees up 21 bits and allows us to shorten the UID struct by an entire
32 bits.

It's not strictly needed (as it's encoded into the length) but I added a
bit for per-pixel lighiting to make my life easier in the following
commits.

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.
