mesa/compiler: rework tear down of builtin/types

The issue we're running into when running CTS is that glsl types are
deleted while builtins depending on them are not.

This happens because on one hand we have glsl types ref counted, but
builtins are not. Instead builtins are destroyed when unloading libGL
or explicitly calling glReleaseShaderCompiler().

This change removes almost entirely any dealing with glsl types
ref/unref by letting the builtins deal with it instead. In turn we
introduce a builtin ref count mechanism. Each GL context takes a
reference on the builtins when compiling a shader for the first time.
It releases the reference when the context is destroyed. It can also
explicitly release those when glReleaseShaderCompiler() is called.

Finally we also take a reference on the glsl types when loading libGL
to avoid recreating glsl types too often.

v2: Ensure we take a reference if we don't have one in link step (Lionel)

5 years agotgsi_to_nir: only update TGSI properties of the current shader stage

tgsi_to_nir: only update TGSI properties of the current shader stage

The implementation introduced in "tgsi_to_nir: be careful about not
losing any TGSI properties silently (v2)" updates all the TGSI properties,
but it didn't take into account that the shader_info structure uses a union
to store the different attributes for each shader stage.

Now we only update the attributes if they affect current shader stage,
avoiding to overwrite members of the union that should be overwritten.
This has created hundreds of regressions in v3d.

For example the TGSI_PROPERTY_VS_BLIT_SGPRS_AMD was overwritting the
same position used by TGSI_PROPERY_CS_FIXED_BLOCK_DEPTH.
