Before it was set if the sctx->framebuffer had a sample count > 1. Now we still require this condition, but we also need either: - GL_MULTISAMPLE to be enabled - to be executing an operation that doesn't depends on GL state using u_blitter. This fixes the arb_sample_shading/sample_mask piglit tests on radeonsi.
