From: Rob Clark <robcl...@freedesktop.org>
At least temporarily, I need to fallback to old compiler still for
relative dest (for freedreno), but I can do relative src temp. Only
a temporary situation, but seems easy/reasonable for tgsi-scan to
track this.

I could always keep temp indirect support on a branch until the RA can
also handle indirect dest. But I would at least like to keep things
split up into smaller patches (and still bisectable).
