[Beignet] [PATCH] Fix a read64/write64 schedule bug.

[Sun, Yi]

This patch introduced two piglit case regression:

./piglit-run.py -t builtin-ulong-mad_sat-1.0.generated tests/all_cl.test t
./piglit-run.py -t builtin-long-mad_sat-1.0.generated tests/all_cl.test t

But indeed it fixed 5 existed bugs:
Program/Execute/gegl-rgb-gamma-u8-to-ragabaf
Program/Execute/Store/store-long16-local
Program/Execute/Store/store-long8-global
Program/Execute/Store/store-ulong16-local
Program/Execute/Store/store-ulong8-global

	Fix a read64/write64 schedule bug.
	Set the read64/write64 correct data type, otherwise, the dependency will

Thanks
