Haojian Wu 9ad1099224 [clangd] No need to query ctor refs in cross-file rename.
Summary:
This patch reverts 2c5ee78de1,
now kythe (https://github.com/kythe/kythe/issues/4381) supports returning ctors refs as part of class references, so
there is no need to query the ctor refs in the index (this would also
make the results worse, lots of duplications)

Haojian Wu e6d0bad843 [clang-rename] Add the USR of incomplete decl to the USRSet.
Summary:
This fixes a clangd rename issue, which is missing the reference of
an incomplete specialization.

Unfortunately, I didn't reproduce this issue in clang-rename, I guess
the input `FoundDecl` of AdditionalUSRFinder is different in clangd vs
clang-rename, clang-rename uses the underlying CXXRecordDecl of the
ClassTemplateDecl, which is fixed in 5d862c042b;
while clangd-rename uses the ClassTemplateDecl.

Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Sam McCall d3260bf5b2 [clangd] Errors in TestTU cause test failures unless suppressed with error-ok.
Summary:
The historic behavior of TestTU is to gather diagnostics and otherwise ignore
them. So if a test has a syntax error, and doesn't assert diagnostics, it
silently misbehaves.
This can be annoying when developing tests, as evidenced by various tests
gaining "assert no diagnostics" where that's not really the point of the test.

This patch aims to make that default behavior. For the first error
(not warning), TestTU will call ADD_FAILURE().

This can be suppressed with a comment containing "error-ok". For now that will
suppress any errors in the TU. We can make this stricter later -verify style.
(-verify itself is hard to reuse because of DiagnosticConsumer interfaces...)
A magic-comment was chosen over a TestTU option because of table-driven tests.

In addition to the behavior change, this patch:
  - adds //error-ok where we're knowingly testing invalid code
    (e.g. for diagnostics, crash-resilience, or token-level tests)
  - fixes a bunch of errors in the checked-in tests, mostly trivial (missing ;)
  - removes a bunch of now-redundant instances of "assert no diagnostics"

[clangd] Fix rename for explicit destructor calls
When triggering rename of the class name in the code with explicit destructor
calls, rename fails. Consider the following piece of code:

```
class Foo;

...

Foo f;
f.~/*...*/Foo();
```

`findExplicitReferences` will report two `ReferenceLoc` for destructor call:
one is comming from `MemberExpr` (i.e. destructor call itself) and would point
to the tilde:

```
f.~/*...*/Foo();
  ^
```

And the second one is pointing to the typename and is coming from `TypeLoc`.

```
f.~/*...*/Foo();
          ^
```

This causes rename to produce incorrect textual replacements. This patch
updates `MemberExpr` handler to detect destructor calls and prevents it
from reporting a duplicate reference.
