mesa: Fix transform feedback of unsubscripted arrays.

It is not explicitly stated in the GL 3.0 spec that transform feedback
can be performed on a whole varying array (without supplying a
subscript).  However, it seems clear from context that this was the
intent.  Section 2.15 (TransformFeedback) says this:

    When writing varying variables that are arrays, individual array
    elements are written in order.

And section 2.20.3 (Shader Variables), says this, in the description
of GetTransformFeedbackVarying:

    For the selected varying variable, its type is returned into
    type. The size of the varying is returned into size. The value in
    size is in units of the type returned in type.

If it were not possible to perform transform feedback on an
unsubscripted array, the returned size would always be 1.

This patch fixes the linker so that transform feedback on an
unsubscripted array is supported.

Fixes piglit tests "EXT_transform_feedback/builtin-varyings
gl_ClipDistance[{4,8}]-no-subscript" and
"EXT_transform_feedback/output_type *[2]-no-subscript".

Note: on back-ends that set
gl_shader_compiler_options::LowerClipDistance (for example i965),
tests "EXT_transform_feedback/builtin-varyings
gl_ClipDistance[{1,2,3,5,6,7}]" still fail.  I hope to address this in
a later patch.

mesa: Add gl_transform_feedback_info::ComponentOffset.

When using transform feedback, there are three circumstances in which
it is useful for Mesa to instruct a driver to stream out just a
portion of a varying slot (rather than the whole vec4):

(a) When a varying is smaller than a vec4, Mesa needs to instruct the
driver to stream out just the first one, two, or three components of
the varying slot.

(b) In the future, when we implement varying packing, some varyings
will be offset within the vec4, so Mesa will have to instruct the
driver to stream out an arbitrary contiguous subset of the components
of the varying slot (e.g. .yzw or .yz).

(c) On drivers that set gl_shader_compiler_options::LowerClipDistance,
if the client requests that an element of gl_ClipDistance be streamed
out using transform feedback, Mesa will have to instruct the driver to
stream out a single component of one of the gl_ClipDistance varying
slots.

Previous to this patch, only (a) was possible, since
gl_transform_feedback_info specified only the number of components of
the varying slot to stream out.  This patch adds
gl_transform_feedback_info::ComponentOffset, which indicates which
components should be streamed out.

Previously, on i965 Gen6 and above, we weren't allocating space for

to clip distances.  This prevented transform feedback from being able

This patch goes aheads and allocates space for gl_ClipVertex in the
VUE on Gen6 and above.  The old behavior is retained on Gen5 and
below, since (a) transform feedback is not yet supported on those
platforms, and (b) those platforms don't currently support
gl_ClipVertex anyhow.

Note: this constitutes a slight waste of VUE space for shaders that
use gl_ClipVertex and don't use transform feedback to capture it.
