ECR #304775 - Wave limiter: Fix crash in CompuBenchCL video composition due to profiling data not collected correctly.

	Gpuvirtual.cpp only collects profiling data when all events have profiling enabled. Fixed it by adding a member to indicate at least one event has profiling enabled and collect profiling data.

	Improved adptation by changing waves/simd only when the last change has been enforced. Also detecting discontinuities in measured data and discard them.
