This combines flags switching off CPU-features randomly with all
other flags on the numfuzz fuzzers.
In a follow up we can add also other interesting flags for testing
more features.

Procs return the result by increasing recursion through result_for.
This CL eliminates that mechanism from the Processor interface and uses boolen
return values for sending tests to signal success or the failure to load the
test into the execution queue.

This adds back an option for interrupt budget available in no-snap
builds. This also adds a fuzzer configuration for numfuzz that enables
fuzzing the interrupt budget option. A new flag --disable-analysis
allows to generally skip the fuzzer's analysis phase, which can be
chosen for interrupt budget, which doesn't support an analysis phase.
