Prior to this CL, call counts at function scope were taken from the FeedbackVector::invocation_count field. This had two major drawbacks: 1. for generator functions, these count the number of resumptions instead of the number of calls; and 2. the invocation count is not maintained in optimized code. The solution implemented here is to add a dedicated call counter at function scope which is incremented exactly once each time the function is called. A minor complication is that our coverage output format expects function-scope counts in the dedicated CoverageFunction object, and not as a CoverageBlock. Thus function-scope block counts are initially marked with magic positions, and later recognized and rewritten during processing. This CL thus fixes reported generator function call counts and enables optimizations in block coverage modes (more to come in a follow-up). Drive-by: Don't report functions with empty source ranges.

Also disables --stress-flush-bytecode on some mjsunit tests which fail when bytecode flushing is stressed due to test invariants.
