llvmpipe: Tighten check for alpha-only formats
The AoS version of ld_build_blend_factor was assuming that if the first channel was alpha, there were no rgb components. Fixes glean/blendFunc on System z. No piglit regressions on x86_64. The shortcut is still used in tests like spec/ARB_framebuffer_object/ fbo-alpha. Signed-off-by: Richard Sandiford <[email protected]>
