- Many tests got broken because of two things:
- AST dump now outputs to stdout, but many tests expected stderr. This was a straightforward fix.
- Many tests call swift with specific parameters; specifically, many call `swift frontend` directly. This makes them go through the compiler in unexpected ways, and specifically it makes them not have primary files, which breaks the new AST dump implementation. This commit adds the old implementation as a fallback for those cases, except it dumps to `stdout` to maintain some consistence.
Finally, the `/test/Driver/filelists.swift` failed for unknown reasons. It seems its output now had some lines out of order, and fixing the order made the test pass. However, as the reasons why it failed are unknown, this fix might not have been a good idea. Corrections are welcome.
when skipping to the end of the interpolated expression.
i.e. Skip the comment as a comment.
Previously, ')' or '"' in comment in interpolated expression used to
cause assertion failure or mis-compilation in no-assert build.

Maintain inner most string literal mode to determine whether we allow
newline character or not.
* Disallow newline after multiline string in string interpolation. (SR-5171)
* Allow unbalanced `"` in multiline string in string interpolation.
This adds support for SE-0168, multi-line string literals.
Extend the lexer to recognize the new literals. Test cases added.
There are still areas for future diagnostic improvement, such as fixits and notes as to why a multi-line string literal will be malformed. Multi-line literals are explicitly forbidden inside of string interpolation, though this may be relaxed in the future.
