Ilya Biryukov fc83aea6a9 [clangd] Fix a crash in Selection
Summary:
The assertion checking that a range of a node is a token range does
not hold in case of "split" tokens, e.g. between two closing template
argument lists (`vector<vector<int>>`).

Haojian Wu ddd64a4f50 [clangd] Fix an assertion failure in Selection.
Summary:
The assertion is triggered when the Decl is null.

Details for the assertion:

Sam McCall 3186e3ceb8 [clangd] Lib to compute and represent selection under cursor.
Summary:
The primary problem this solves is to expose the codeAction selection to
AST-based refactorings in a way that makes it easy and efficient for them to
bind to the right parts of the AST.

It should also allow us to make XRefs based features (textDocument/definition)
more robust, more easily implement textDocument/typeDefinition etc.
As an example, template parameter references can be identified without special
handling.
There should be slight speedup too: we can prune most of the AST traversal
in most cases.

Elephant in the room: this is similar-but-different to Tooling/Refactoring/ASTSelection.
That captures a smaller set of AST nodes, has a slightly different way of
representing selections, and generally has mare features and does more work.
The overall shape is pretty similar, and yet I can't quite get to behave as I
expect.
