Second installment of this series.
Patches 1-6 are trivial general cleanups I came across while doing this,
patches 7-10 are the real thing.
The changes from the last version are:
? Move from a white list of tests to run to a black list of tests to skip
? Name the environment variable that controls the simulation behaviour to
INTEL_SIMULATION to have a chance to share the name with the piglit tests.
