Add support for -polly-codegen-perf-monitoring. When performance monitoring is enabled, we emit performance monitoring code during code generation that prints after program exit statistics about the total number of cycles executed as well as the number of cycles spent in scops. This gives an estimate on how useful polyhedral optimizations might be for a given program. Example output: Polly runtime information ------------------------- Total: 783110081637 Scops: 663718949365 In the future, we might also add functionality to measure how much time is spent in optimized scops and how many cycles are spent in the fallback code.
