	* #include an absolute path didn't work - because paths were taken to always be relative. * WIP: First pass in supporting output of line error information. * Add support for lexing to better be able to indicate SourceLocation information. * Fix lexer usage in DiagnosticSink in C++ extractor. * Update diagnostics tests to have line location info. * Fixed test expected output that now have source location information in them. * Better handling of tab. * Fix test expected results for tabbing change. * DiagnosticLexer -> DiagnosticSink::SourceLocationLexer Added line continuation tests. * Fix typo. * Added String::appendRepeatedChar * Change to rerun tests.

2018-04-20	Diagnose use of an implicit cast as an argument for an `out` parameter (#516)	Tim Foley
	Work on #499 Two big fixes here: * The logic for checking constraints on `out` arguments wasn't actually triggering because it relied on function parameters being given an `OutType` if they are marked `out`, but the code wasn't actually doing that. Fixing the computation of types for functions resolved that issue. * Next, I added a specific diagnostic to follow up the "expected an l-value" error to let the user know that their argument was implicitly converted, and that is why it doesn't count as an l-value in Slang's rules. I've added a test case to ensure that we retain this diagnostic until we can do a true fix for the issue. The right long-term fix is to have an AST representation of all the implicit casts involved (e.g., in both directions for an `inout` parameter), and then have the IR generate explicit code for the conversions in each direction (the `LoweredVal` representation can handle this sort of thing).
