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:
