The TGSI FBFETCH instruction is used for implementing framebuffer-reads
when doing for instance advanced blends. It's used by both
EXT_shader_framebuffer_fetch_non_coherent and
KHR_blend_equation_advanced.
Sadly, libepoxy doesn't yet support the glFramebufferFetchBarrierEXT
function needed to implement this on top of
EXT_shader_framebuffer_fetch_non_coherent itself, so let's just implement
it on top of EXT_shader_framebuffer_fetch instead for now.
This means that we'll have slightly higher requirements for enabling
this functionality than the level of functionality we provide through it.

This mostly consists of adding local memory support, and
support for the compute system values.
The req_local_mem need to be gotten from the guest side
and passed into the shader compile so we can size the
shared memory correctly.

TGSI has a different model for precise than GLSL, so we have to mark
all outputs that has gotten an precise operation output to it as
precise.
This only implements part of the 'precise' keyword (still lacking
support on individual operations), but it's enough to pass some dEQP
tests, in particular:

If a shader uses TGSI_INTERPOLATE_LOC_SAMPLE, we need to emit
the "sample"-keyword for the input-variable in the fragment
shader.
Since the "sampler"-keyword is a GLSL 4.00 feature, this
requires us to enable GL_ARB_gpu_shader5. Unfortunately, opting
in carefully on this is a bit trickier than for most other
extensions, because we patch up vertex, geometry or tesselation
evaluation shader outputs to match the fragment shader inputs.
Since the previous patch adds padding for the require-statement
directly after the #version string, we can just overwrite that
padding with the require statement.
This fixes the following tests:
