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 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.
