[Piglit] [PATCH 0/4] ARB_gl_spirv: xfb tests

[Alejandro Piñeiro]

Hi,

this is the third series that includes tests for the ARB_gl_spirv
extension. Note that this depends on the pending-to-review first
series (basics+uniforms) and second (atomic counters). The three
series are included on the following branch:

https://github.com/Igalia/piglit/tree/arb_gl_spirv-series3-xfb-v1

It is worth to note that this series introduces a change on the tests
we are including. Until now all the tests were tests in shader_test
format run by shader_runner. But right now shader_runner doesn't have
too much support for transform feedback/geometry streams testing, and
adding support on a generic way would be far from trivial.

For that reason we preferred to modify existing XFB/Geometry Stream
tests, but adding the capability to load GLSL and SPIR-V shaders. In
order to do that, we moved the GLSL code they were using to a
shader_test, that also includes now the SPIR-V, and added utilities to
load shaders from a shader_test, and to assemble the SPIR-V from the
assembler format. The latter is refactored from shader_runner.

So from now we would have more that one consumer of the shader_test
format: the generic shader_runner, and some custom one used for really
specific features.
