This was a very serious bug. We were always doing the viewport
transformations on the first output of the vertex shader. That means
that every application that was storing position in anything but
OUT[0] was outputing untransformed vertices and had broken output
for whatever it was storing at OUT[0]. Correctly take into
consideration where the vertex position is actually stored.

There can be more stream output decls than shader outputs because
individual components from them can be split and distributed
among different so buffers.

Before, we'd incorrectly generate an error if we we tried to
replace a non-4x4 block near the edge of a NPOT compressed texture.
For example, if the dest image was 15 texels wide and xoffset=12
and width=3 we'd incorrectly generate GL_INVALID_OPERATION.
Verified with new tests added to piglit s3tc-errors test.
Note: This is a candidate for the stable branches.

After more thought/discussion, it seems it is better to handle this sort
of stuff in the state tracker.
So this reverts commit 12096f334b, except the
variant->key -> key shorthands.
This is a simple shader compiler that performs almost zero optimizations. The
generated code is usually much larger comparing to that generated by i965.
The generated code also requires many more registers.
Function-wise, it lacks register spilling and does not support most TGSI
indirections. Other than those, it works alright.

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.

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.
