This is so that precise coverage starts with a clean slate.
The old behavior can be emulated by calling getBestEffortCoverage
before starting precise coverage.

Consider:
function f() {
return;
}
This CL ensures that the closing brace is considered as covered by
introducing a special case for open-ended range rewrites when the
parent range is the function range itself.

Function-granularity coverage skips functions that are both uncovered
and have an uncovered parent. This optimization needs to be tweaked once
block coverage and incremental collection is in play, as it is possible
to have a function with invocation_count == 0 (i.e. uncovered at
function granularity) that still has relevant block-granularity
coverage.

This adds a new binary block coverage mode (in addition to the existing count
block coverage), as well as a few transformation passes to reduce the number of
uselessly reported ranges.

This CL adds a few transformations that clean up the set of reported
source ranges. Duplicates, empty, and uncovered ranges are removed, and
nested/consecutive ranges are merged if possible.

This piggy-backs on top of existing precise and best-effort coverage to expose
block coverage through the inspector protocol.
Coverage collection now implicitly reports block-granularity coverage when
available. A new 'isBlockCoverage' property on Inspector's FunctionCoverage
type specifies the granularity of reported coverage.
For now, only count-based block coverage is supported, but binary block
coverage should follow soon.
Support is still gated behind the --block-coverage flag.
