The above commit regresses the following piglit tests:
vload-half-private.cl
vload-half-local.cl
vload-short-private.cl
vload-short-local.cl
vload-ushort-private.cl[0]
vload-ushort-local.cl
Note that the regression happens only on Raven (at least carrizo/iceland is
OK),
and only vec2 tests are affected.
I've verified to switching the options off on
954735141519398580615e0907a85ed0972b50cb
Fixes the issue.
