turnip: depth/stencil regressions
One of these dynamic render commits
broke these tests:
GTF-GL46.gtf30.GL3Tests.packed_depth_stencil.packed_depth_stencil_copyteximage,Fail
GTF-GL46.gtf30.GL3Tests.packed_depth_stencil.packed_depth_stencil_getteximage,Fail
GTF-GL46.gtf30.GL3Tests.packed_depth_stencil.packed_depth_stencil_readpixels,Fail
KHR-GL46.packed_depth_stencil.verify_copy_tex_image.depth24_stencil8,Fail
KHR-GL46.packed_depth_stencil.verify_copy_tex_image.depth32f_stencil8,Fail
KHR-GL46.packed_depth_stencil.verify_get_tex_image.depth24_stencil8,Fail
KHR-GL46.packed_depth_stencil.verify_get_tex_image.depth32f_stencil8,Fail
KHR-GL46.packed_depth_stencil.verify_read_pixels.depth24_stencil8,Fail
KHR-GL46.packed_depth_stencil.verify_read_pixels.depth32f_stencil8,Fail
KHR-GLES3.packed_depth_stencil.verify_read_pixels.depth24_stencil8,Fail
KHR-GLES3.packed_depth_stencil.verify_read_pixels.depth32f_stencil8,Fail
I can't bisect further because turnip crashes internally and the series is not bisectable.
