the same performance.  The clipper comes directly after SOL anyway,

mesa/glsl: stop using GL shader type internally

Instead use the internal gl_shader_stage enum everywhere. This
makes things more consistent and gets rid of unnecessary
conversions.

Ideally it would be nice to remove the Type field from gl_shader
altogether but currently it is used to differentiate between
gl_shader and gl_shader_program in the ShaderObjects hash table.

not set bind flags correctly, and this is more or less unfixable due to GL.

This caused a bug with piglit arb_uniform_buffer_object-rendering-dsa

but it caused us to miss updates to fs UBOs completely, since the
corresponding buffer didn't have the appropriate bind flag set (thus we
wouldn't check if it is indeed currently bound).
See the discussion about this starting here:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/119829.html

So, update the bind flags when we detect such usage.
Note we update this value for now only in places which matter for us - that
is creating sampler/surface view, or binding constant buffer. There's plenty
more places (setting streamout buffers, vertex/index buffers, ...) where
things can be set with the wrong bind flags, but the bind flags there never
matter.

While here also make sure we only set dirty constant bit when it's a fs
constant buffer - totally doesn't matter if it's vs/gs.

I haven't found any mention of this in the hardware docs, but
experimentally what seems to be going on is that when the per-thread
scratch slot size is changed between two pipelined draw calls, shader
invocations using the old and new scratch size setting may end up
being executed in parallel, causing their scratch offset calculations
to be based in a different partitioning of the scratch space, which
can cause their thread-local scratch space to overlap leading to
cross-thread scratch corruption.

I've been experimenting with alternative workarounds, like emitting a
PIPE_CONTROL with DC flush and CS stall between draw (or dispatch
compute) calls using different per-thread scratch allocation settings,
or avoiding reuse of the scratch BO if the per-thread scratch
allocation doesn't exactly match the original.  Both seem to be as
effective as this workaround, but they have potential performance
implications, while this should be basically for free.

Fixes over 40 failures in our CI system with spilling forced on
(including CTS, dEQP and Piglit failures) on a number of different
platforms from Gen4 to Gen9.  The 'glsl-max-varyings' piglit test
