Three-source instructions have a vertical stride overloaded to 4, which
prevents directly using vec4 uniforms as arguments. Instead we need to
insert a MOV instruction to do the replication for the three-source
instruction.
With this in place, we can use three-source instructions in the vertex
shader. While some thought needs to go into deciding whether its better
to use a three-source instruction rather than a sequence of equivalent
instructions (when one or more sources are uniforms or immediates), this
will allow us to skip a lot of ugly lowering code and use the BFE and
BFI2 instructions directly.

We don't support pre-2.6 kernels anyway - the install docs say 2.6.28
for DRI - and apparently this confuses ld.so's sorting when multiple
libGLs are installed. Just remove it.
Note: this is a candidate for the stable branches.

New textures or vertex buffers don't always require patching and
re-emitting the shaders. So do a better job of figuring out when we
actually have to patch the shader.

Removes 75/78 state-dependent recompiles in GLB2.7 (the remaining 3 are
due to FBO-rendering size predictions). We currently expose
GL_ARB_color_buffer_float on GL core, so we may mis-predict there, but I'm
about to send a patch for removing that silly extension in that case.

clang is supports most gcc options / extensions, with a some exceptions.
The biggest advantage of using clang is that compilation times are much

The previous approach of using the dst register as an intermediate
temporary doesn't work in a lot of cases. For example, if the dst
register is the same as one of the src registers.
For now, just simplify it and always allocate a new register to use as
an intermediate. In some cases this will result in more registers used
than required. I think the best solution would be to implement an
optimization pass to reduce the number of registers used, which would
also solve the problem we have now of not being able to use GPRs that
are assigned for TGSI_FILE_INPUT.

Really this should be set based on buffer format, not on color vs
depth/stencil. Probably there should be more formats that set the bit
