glsl: reuse main extension table to appropriately restrict extensions

Previously we were only restricting based on ES/non-ES-ness and whether
the overall enable bit had been flipped on. However we have been adding
more fine-grained restrictions, such as based on compat profiles, as
well as specific ES versions. Most of the time this doesn't matter, but
it can create awkward situations and duplication of logic.

Here we separate the main extension table into a separate object file,
linked to the glsl compiler, which makes use of it with a custom
function which takes the ES-ness of the shader into account (thus
allowing desktop shaders to properly use ES extensions that would
otherwise have been disallowed.) We can also now use this logic to
generate #define's for all supported extensions automatically, removing
the duplicate (and often inaccurate) list in glcpp.

The effect of this change should be nil in most cases. However in some
situations, extensions like GL_ARB_gpu_shader5 which were formerly
available in compat contexts on the GLSL side of things will now become
inaccessible.

This regresses two ES CTS tests:

  ES3-CTS.shaders.shader_integer_mix.define
  ES31-CTS.shader_integer_mix.define

however that is due to them using #version 100 instead of 300 es. As the
extension is only defined for ES3, I believe this is the correct
behavior.

docs: Put swr back on the GL_ARB_texture_buffer_object_rgb32 list.

commit d1fbd4cdb1bdb8041362a8e5f05833c43a39c9a6.

glsl: subroutine types cannot be compared

subroutine variables are to be used just in the way functions are
called. Although the spec doesn't say it explicitely, this means that
these variables are not to be used in any other way than those left
for function calls. Therefore, a comparison between 2 subroutine
variables should also cause a compilation error.

From The OpenGL® Shading Language 4.40, page 117:

  "  To use subroutines, a subroutine type is declared, one or more
     functions are associated with that subroutine type, and a
     subroutine variable of that type is declared. The function
     currently assigned to the variable function is then called by
     using function calling syntax replacing a function name with the
     name of the subroutine variable. Subroutine variables are
     uniforms, and are assigned to specific functions only through
     commands (UniformSubroutinesuiv) in the OpenGL API."

From The OpenGL® Shading Language 4.40, page 118:

  "  Subroutine uniform variables are called the same way functions
     are called. When a subroutine variable (or an element of a
     subroutine variable array) is associated with a particular
     function, all function calls through that variable will call that
     particular function."

mesa: Add GL_BGRA_EXT to the list of GenerateMipmap internal formats.

The GL_EXT_texture_format_BGRA8888 extension specification defines a
GL_BGRA_EXT unsized internal format (which is a little odd - usually
BGRA is a pixel transfer format).  The extension is written against
the ES 1.0 specification, so it's a little hard to map, but I believe
it's effectively adding it to the table used here, so we should allow
it here as well.

Note that GL_EXT_texture_format_BGRA8888 is always enabled (dummy_true),
so we don't need to check if it's enabled here.

This fixes mipmap generation in Skia and ChromeOS.

nir: Add a base const_index to shared atomic intrinsics.

Commit 52e75dcb8c04c0dde989970c4c587cbe8313f7cf made nir_lower_io
start using nir_intrinsic_set_base instead of writing const_index[0]
directly.  However, those intrinsics apparently don't /have/ a base,
so this caused assert failures.

However, the old code was happily setting non-existent const_index
fields, so it was pretty bogus too.

Jason pointed out that load_shared and store_shared have a base,
and that the i965 driver uses that field.  So presumably atomics
should have one as well, so that loads/stores/atomics all refer
to variables with consistent addressing.
