[Mesa-dev] [PATCH 08/13] radeonsi: remove interp_at_sample from the key, use TGSI_INTERPOLATE_LOC_SAMPLE

[Marek Olšák]

From: Marek Olšák <marek.olsak at amd.com>

st/mesa has the same flag in its shader key, we don't need to do it
in the driver anymore.

Instead, use TGSI_INTERPOLATE_LOC_SAMPLE, which is what st/mesa sets.
