If the assertion was hit, it probably meant that we were unable to allocate
or map a vertex buffer. Instead of dying in a debug build, issue a warning
and continue.
We need to pass the pre-projection matrix clip planes into the driver,
instead of the post for the case we have a vertex shader that writes clip
vertex.

The various l-value errors this was designed to catch are now caught
by other means. Marking the temporaries as read-only now just
prevents sensible error messages from being generated. It's

Everything about this that we have tests for works except for the
deprecated metaops. The conclusion we came to on IRC sounded like we
were OK with turning it on as long as core functionality works. The
remaining failures (copypixels, drawpixels) should just be a matter of
finishing the MapRenderbuffer for them.

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.

Previously we were using
gl_transform_feedback_object::Buffers[i]->Name to service an indexed
get request for GL_TRANSFORM_FEEDBACK_BUFFER_BINDING. However, if no
buffer has been bound, gl_transform_feedback_object::Buffers[i] is
NULL, so this was causing a segfault.
This patch switches to using
gl_transform_feedback_object::BufferNames[i], which is equal to
gl_transform_feedback_object::Buffers[i]->Name if
gl_transform_feedback_object::Buffers[i] is not NULL, and 0 if it is
NULL.
