713c30b389 [clangd] Don't consider class template params part of constructor name.
Summary:
This is shorter and usually the extra info is noise.
There are cases where the params become type-parameter-0-0 that are hard to fix.

This affects a few features:
 - 'name' field in structured hover API (not exposed yet)
 - 'name' field in locateSymbolAt (not exposed in LSP)
 - 'document/symbol' - the symbol is hierarchically nested in the class
   template, or written as foo<t>::foo when defined out-of-line.

Added a test case for hover from https://github.com/clangd/clangd/issues/76.
This patch fixes one field, but no fewer than four others are wrong!
I'll fix them...

ad9fd32009 [clangd] Fix SelectionTree behavior on constructor init-lists.
Summary:
For the constructor Foo() : classmember(arg) {}

The AST looks like:
 - CXXCtorInitializer  classmember(arg)
   - CXXConstructExpr  classmember(arg)
     - DeclRefExpr:                arg

We want the 'classmember' to be associated with the CXXCtorInitializer, not the
CXXConstructExpr. (CXXConstructExpr is known to have bad ranges).
So just early-claim it.

Thanks @hokein for tracking down/reducing the bug.

509efe5d8e [clangd] Add isHeaderFile helper.
Summary:
we have a few places using `ASTCtx.getLangOpts().IsHeaderFile` to
determine a header file, but it relies on "-x c-header" compiler flag,
if the compilation command doesn't have this flag, we will get a false
positive. We are encountering this issue in bazel build system.

To solve this problem, we infer the file from file name, actual changes will
come in follow-ups.

Summary:
This doesn't cover decls in diagnostics, which use NamedDecl::getNameForDiagnostic().

bbcbb10e2d [clangd] Ignore more implicit nodes in computing selection.
Summary:
The DeclRefExpr for the callee of overloaded `operator()` and `operator[]` are
assigned the range of the paren/bracket lists in the AST.
These are better thought of as implicit (at least `()` - `[] is murkier).
But there's no bit on Expr for implicit, so just ignore them on our side.

While here, deal with the case where an implicit stmt (e.g. implicit-this)
is wrapped in an implicit cast. Previously we ignored the statement but not
the cast, and so the cast ended up being selected.

489449c28a [libTooling] Further simplify Stencil type and introduce MatchComputation.
Summary:
This revision introduces a new interface `MatchComputation` which generalizes
the `Stencil` interface and replaces the `std::function` interface of
`MatchConsumer`. With this revision, `Stencil` (as an abstraction) becomes just
one collection of implementations of
`MatchComputation<std::string>`. Correspondingly, we remove the `Stencil` class
entirely in favor of a simple type alias, deprecate `MatchConsumer` and change
all functions that accepted `MatchConsumer<std::string>` to use
`MatchComputation<std::string>` instead.

Summary:
There is a regression from https://reviews.llvm.org/D68467. Unlike class
forward declarations, function ducomentation is written in the declaration in
headers, the function definition doesn't contain any documentation, cases like:

```
foo.h
// this is foo.
void foo();
foo.cc

void foo() {}
```
we should still show documentation from the foo declaration.

Melanie Blower
759948467e Reapply "Fix crash on switch conditions of non-integer types in templates"
This patch reapplies commit 76945821b9. The first version broke
buildbots due to clang-tidy test fails. The fails are because some
errors in templates are now diagnosed earlier (does not wait till
instantiation). I have modified the tests to add checks for these
diagnostics/prevent these diagnostics. There are no additional code
changes.

Summary of code changes:

Clang currently crashes for switch statements inside a template when the
condition is a non-integer field member because contextual implicit
conversion is skipped when parsing the condition. This conversion is
however later checked in an assert when the case statement is handled.
The conversion is skipped when parsing the condition because
the field member is set as type-dependent based on its containing class.
This patch sets the type dependency based on the field's type instead.

This patch fixes Bug 40982.

87e0cb4f1a [clangd] Implement semantic highlightings via findExplicitReferences
Summary:
To keep the logic of finding locations of interesting AST nodes in one
place.

The advantage is better coverage of various AST nodes, both now and in
the future: as new nodes get added to `findExplicitReferences`, semantic
highlighting will automatically pick them up.

The drawback of this change is that we have to traverse declarations
inside our file twice in order to highlight dependent names, 'auto'
and 'decltype'. Hopefully, this should not affect the actual latency
too much, most time should be spent in building the AST and not
traversing it.
