with llvmpipe

The demo in question is src/samples/stencil.c found in the demo repository.  With swrastg_dri.so,

  $ LIBGL_ALWAYS_SOFTWARE=1 GALLIUM_DRIVER=softpipe ./stencil

gives correct result, but

  $ LIBGL_ALWAYS_SOFTWARE=1 GALLIUM_DRIVER=llvmpipe ./stencil

gives incorrect result on my x86 machine.

st/vega exhibits similar artifacts when used with llvmpipe.
