de9b936d76 QLDoc tidy up Declaration.qll 
Mostly just adding backticks in QLDoc comments.  I'm trying out the edit-in-github workflow @jbj showed me, which seems like it will be a quicker way to do minor changes like these.

912679ef8c C++: Two IR fixes 
My original fix in https://github.com/Semmle/ql/pull/1661 fixed my minimal test case, but did not fix the original failure in a Linux snapshot. The real fix is to simply not create a `TranslatedDeclarationEntry` for an extern declaration, and have `TranslatedDeclStmt` skip any such declarations. I've added a regression test for that case (multiple extern declarations with same location in a macro expansion, with control flow between them). I did verify that it generates correct IR, and that it fixes all of the "use not dominated by definition" failures in Linux.

The underlying extractor bug, that caused the above issue also caused PrintAST to print garbage. I've worked around the bug in PrintAST.qll.

I've also fixed a bug in the control flow for `try`/`catch`, where there was missing flow from the `CatchByType` of the last handler of a `try` to the enclosing handler (or `Unwind`). Hat tip to @AndreiDiaconu1 for spotting this bug.

972f0d97d3 C++: Stop generating NoOp instructions for declarations of externs 
Previously, where we had a function-scoped `DeclarationEntry` for an extern variable or function, we would generate a `NoOp` instruction for it. There's nothing wrong with this by itself, although it was unnecessary. However, I've hit an extractor issue (Jira ticket already opened) that commonly causes multiple `DeclStmt`s to share a single `DeclarationEntry` child on extern declarations, so removing the `NoOp` instructions is an easy way to work around the extractor issue.

832807401b C++: Move imports from instantiated pyrameterized modules into separate file 
Rather than have IR.qll (which depends on the flavor) import EdgeKind.qll (which does not) with an non-relative import, I've moved these imports into internal.IRImports relative to IR.qll. These imports files can be shared across flavors within one language, but are different between C# and C++ due to the difference in paths.
