Previously, we conditionally set up the SF pipline stage with a

causing the clip distance VUE slots to be skipped if present. This
was an extremely minor savings (it saved the SF unit from reading 2
vec4s out of the URB, but it didn't affect any computation, since we
only instruct the SF unit to perform interpolation on VUE slots that
are actually used by the fragment shader).
GLSL 1.30 requires an interpolated version of gl_ClipDistance to be
available for reading in the fragment shader, so we need the SF's
urb_entry_read_offset to be 1 when the fragment shader reads from
gl_ClipDistance.
This patch just unconditionally sets the urb_entry_read_offset to 1 in
all cases; this is sufficient to make gl_ClipDistance available to the
fragment shader when it is needed, and the performance loss should be
negligible when it isn't.

i965: Set up clip distance VUE slots appropriately for gl_ClipDistance.
When gl_ClipDistance is in use, the contents of the gl_ClipDistance
array just need to be copied directly into the clip distance VUE
slots, so we re-use the code that copies all other generic VUE slots
(this has been extracted to its own method). When gl_ClipDistance is
not in use, the vertex shader needs to calculate the clip distances
based on user-specified clipping planes.
This patch also removes the i965-specific enum values
BRW_VERT_RESULT_CLIP[01], since we now have generic Mesa enums that
serve the same purpose (VERT_RESULT_CLIP_DIST[01]).

mesa: Add a flag to indicate whether a program uses gl_ClipDistance.
GLSL 1.30 requires us to use gl_ClipDistance for clipping if the
vertex shader contains a static write to it, and otherwise use
user-defined clipping planes. Since the driver needs to behave
differently in these two cases, we need a flag to record whether the
shader has written to gl_ClipDistance.
The new flag is called UsesClipDistance. We initially store it in
gl_shader_program (since that is the data structure that is available
when we check to see whethe gl_ClipDistance was written to), and we
later copy it to a flag with the same name in gl_vertex_program, since
that is a more convenient place for the driver to access it (in i965,
at least).

glsl: Implement a lowering pass for gl_ClipDistance.
In i965 GEN6+ (and I suspect most other hardware), gl_ClipDistance
needs to be laid out as a pair of vec4's (the first containing clip
distances 0-3, and the second containing clip distances 4-7).
However, it is declared in GLSL as an array of 8 floats.
This lowering pass acts at the GLSL level, modifying the declaration
of gl_ClipDistance so that it is an array of vec4's rather than an
array of floats, and renaming it to gl_ClipDistanceMESA. In addition,
it modifies all accesses to the array so that they access the
appropiate component of one of the vec4's.
Since some hardware may not internally represent gl_ClipDistance as a
pair of vec4's, this lowering pass is optional. To enable it, set the
LowerClipDistance flag in gl_shader_compiler_options to true.

glsl hierarchical visitor: Do not overwrite base_ir for parameter lists.
This patch fixes a bug in ir_hirearchical_visitor: when traversing an
exec_list representing the formal or actual parameters of a function,
it modified base_ir to point to each parameter in turn, rather than
leaving it as a pointer to the enclosing statement. This was a
problem, since base_ir is used by visitor classes to locate the
statement containing the node being visited (usually so that
additional statements can be inserted before or after it). Without
this fix, visitors might attempt to insert statements into parameter
lists.
