Frontend outputs source-as-compiled, and source-ranges file with function body ranges and ranges that were unparsed in secondaries. Driver computes diffs for each source file. If diffs are in function bodies, only recompiles that one file. Else if diffs are in what another file did not parse, then the other file need not be rebuilt.
