This commit allows compliance test-cases to be written that specify source-map mappings between the source and generated code. To check a mapping, add a `// SOURCE:` comment to the end of a line: ``` <generated code> // SOURCE: "<source-url>" <source code> ``` The generated code will still be checked, stripped of the `// SOURCE` comment, as normal by the `expectEmit()` helper. In addition, the source-map segments are checked to ensure that there is a mapping from `<generated code>` to `<source code>` found in the file at `<source-url>`. Note: * The source-url should be absolute, with the directory containing the TEST_CASES.json file assumed to be `/`. * Whitespace is important and will be included when comparing the segments. * There is a single space character between each part of the line. * Newlines within a mapping must be escaped since the mapping and comment must all appear on a single line of this file.
