Research direction
Start at lib/source-node.js#L396-L417 and inspect how end-of-line mappings are added by toStringWithSourceMap. Compare sourcemaps produced with and without those mappings, then use SourceMapConsumer to determine whether both forms remain valid and record whether the mappings are needed.

Description
We add a mapping for each end of line here:
https://github.com/mozilla/source-map/blob/4e304db915cecd42505feb007766a034395c6eb7/lib/source-node.js#L396-L417
in a project of mine, I overridden this and was not doing this, and the SourceMapConsumer seems to be fine with the sourcemap that is being generated.
