This makes a bunch of changes to package syntax to tweak line numbers for AST nodes. For example, short variable declaration statements are now associated with the location of the ":=" token, and function calls are associated with the location of the final ")" token. These help satisfy many unit tests that assume the old parser's behavior. Because many of these changes are questionable, they're guarded behind a new "gcCompat" const to make them easy to identify and revisit in the future. A handful of remaining tests are too difficult to make behave identically. These have been updated to execute with -newparser=0 and comments explaining why they need to be fixed. all.bash now passes with both the old and new parsers.
