This improves the performance of the printAst.ql query by excluding a lot of string concatenations that happen in files unrelated to the one the user is interested in printing.
This is supposed to help the performance of the AST Viewer on bigger databases.
This commit extends developers ability to use jump-to-def in C/C++ files opened in the VSCode extension.
Before, jump-to-def starting with code in a template instantiation did not work.
Furthermore, this fixes a bug, as the list of all references of a location did not include template instantiations.
Two interesting things happened while doing this:
1. I found out that you can't use the same name to define a submodule as any
parent module. So we need give unique names to the top-level module, and the
module for modeling the `flask.Flask` class. I randomly choose a new name for
the top-level module to get things moving (and not be stuck in bikeshedding
forever).
2. With this new setup, I wanted to expose the `route` and `add_url_rule`
methods on instances of `flask.Flask`. It wasn't quite obvious how to do so. I
simply lumped them next to `classRef()` and `instance()`, without too much
care. I did consider putting them inside a `instance` module, which would allow
you to access them by `flask::Flask::instance::route()`, but I wasn't quite
sure, and just did something easy to get moving.
This fixes the IR generation for member accesses where the qualifier is a prvalue that is _not_ the load of a `TemporaryObjectExpr`. We synthesize a temporary variable during IR generation instead. It fits into the IR construction code at the same spot as `TranslatedLoad`, since it's basically the opposite of `TranslatedLoad` (prvalue->glvalue instead of vice versa). Note that array prvalues require special treatment.
This fixes some consistency errors in the `syntax-zoo`. It introduces three new ones in `dataflow-ir-consistency.expected`, but those are along the same lines as tons of existing failures.
