This change fixes the translator to search for the ES3.2 variant of the builtin when the shader is an ES3.2 shader Test: dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.default_framebuffer --deqp-gl-config-name=rgba8888d24s8ms4 Test: dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at_offset.at_sample_position.default_framebuffer --deqp-gl-config-name=rgba8888d24s8ms4 Bug: angleproject:5637 Change-Id: I2b56ee4d2196fa717748c7205745169de562cb22 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3421526 Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
