From: Eduardo Lima Mitev <el...@igalia.com>
This is the main fork of the shader compilation code-path, where a NIR
shader is obtained by calling spirv_to_nir() or glsl_to_nir(),
depending on its nature..
v2: Use 'spirv_data' member from gl_linked_shader to know which method
to call. (Timothy Arceri)
