1. sysfs half/full switch.
4. execbuf without I915_EXEC_USE_PREDICATE
5. execbuf with I915_EXEC_USE_PREDICATE

v2: include more tests and s/GT_FULL/USE_PREDICATE
v3: make it more reliable and fix few comments
v4: use number of slices on (1,2) instead of half and full strings.

With the new namimg conventions I'd give this a pm_ prefix.
