[Mesa-dev] [PATCH] i965/emit: Assert that src1 is not an MRF after doing the MRF->GRF conversion

[Jason Ekstrand]

When emitting texturing from indirect texture units, we need to be able to
scratch around in the header message.  Since we only do this for >= HSW,
this is ok since there are no MRFs.
