[Mesa-dev] [PATCH 1/5] intel/eu: Use EXECUTE_1 for JMPI

[Jason Ekstrand]

There doesn't seem to be a good reason for using EXECUTE_2 for JMPI and
brw_fs_generator manually stomps it to 1.  This is a functional change
because it changes all of the clip and SF programs on gen4-5 to use
EXECUTE_1 for JMPI.  Piglit says that this is ok.
