8034e7d6f1 glsl: Convert TES gl_PatchVerticesIn into a constant when using a TCS.
When a TCS is present, the TES input gl_PatchVerticesIn is actually a
constant - it's simply the # of output vertices specified by the TCS
layout qualifiers.  So, we can replace the system value with a constant,
which may allow further optimization, and will likely be more efficient.

If the TCS is absent, we can't do this optimization.

Currently, these arrays in gl_shader and gl_shader_program hold both
UBOs and SSBOs, so this looks like a better name. We were already
using NumBufferInterfaceBlocks in gl_shader_program, so this makes
things more consistent as well.

In a later patch we will add {Num}UniformBlocks and
{Num}ShaderStorageBlocks which will contain only references to
UBOs and SSBOs respectively that will provide backends with
a separate index space for both types of objects.

c3294ca5a1 glsl: Handle attribute aliasing in attribute storage limit check.
In various versions of OpenGL and GLSL, it's possible to declare
multiple VS input variables with aliasing attribute locations.

So, when computing the storage requirements for vertex attributes,
we can't simply add up the sizes.  Instead, we need to look at the
enabled slots.

This patch begins tracking which attributes are double types that
are larger than 128-bits (i.e. take up two vec4 slots).  We then
count normal attributes once, and count the double-size attributes
a second time.

Fixes deQP functional.attribute_location.bind_aliasing.max_cond_* tests
on i965, which regressed with commit ad208d975a.

No Piglit changes on llvmpipe (which actually supports dvecs).

18c5cdb943 glsl: add variable mode check to build_stageref
Currently stage reference mask is built using the variable name
only. However it can happen that input of one stage has same name
as output from another stage. Adding check of variable mode makes
sure we do not pick wrong variable.

Fixes some subcases from
   ES31-CTS.program_interface_query.no-locations

60266863d8 glsl: add uniform and program resource support (v2)
This adds linker support for subroutine uniforms, they
have some subtle differences from real uniforms, we also hide
them and they are given internal uniform names.

This also adds the subroutine locations and subroutine uniforms
to the program resource tracking for later use.

v1.1: drop is_subroutine_def

v2: handle explicit location properly, ARB_explicit_location
has a lot of language for subroutine shaders.
Calculate a link time the number of compatible subroutines
for a uniform, to make program resource easier later.

disallows use of the builtin barrier() function in all the
