So tess shaders have some circular dependencies,
TCS needs the TES primitive mode
TES needs the TCS vertices out
This builds the nir for each shader first to get the
info, executes a tes specific nir pass, then builds
the LLVM shaders.

This ports the code from radeonsi to build the if/endif,
and ports the tess factor emission code. This code has
an optimisation TODO that we can deal with later.

This adds support for the tessellation inputs/outputs to the
shader compiler, this is one of the main pieces of the patch.
It is very similiar to the radeonsi code (post merge we should
consider if there are better sharing opportunities). The main
differences from radeonsi, is that we can have "compact" varyings
for clip/cull/tess factors, and we have to add special handling
for these.
This consists of treating the const index from the deref different
depending on the compactness.

This calculates the pipeline state for tessellation.
It moves the gs ring calculation down to below
where the tessellation shaders will be compiled,
as it needs the info from those shaders.

Some versions of MinGW-w64 such as 5.3.1 and 6.2.0 produce bad code
with -O2 or -O3 causing a random driver crash when running programs
that use GLSL. Most Mesa demos in the glsl/ directory trigger the
bug, but not the fragcoord.c test.
Use a #pragma to force -O1 for this file for later MinGW versions.
Luckily, this is basically one-time setup code. I suspect the bug
is related to the sheer size of this file.
This should let us move to newer versions of MinGW-w64 for Mesa.

Fix a bug that was caused by a type mismatch in the shift count between
GLSL and TGSI. I briefly considered adjusting the TGSI semantics, but
since both LLVM and AMD GCN require both arguments to be of the same type,
it makes more sense to keep TGSI as-is -- it reflects the underlying
implementation better.
I'm also sending out piglit tests that expose this error.

The commit mentioned below required the __DRI2FlushExtension to have
version 4 or above, for GBM functionality. That broke GBM with some
classic dri drivers. Relax that requirement so that we only flush
after unmap if we have version 4 or above. Drivers that require the flush
for correct functionality should implement the desired version.
