Nico Weber 9d80a722d7 Make the last to clangd unit tests pass on Windows.
(Some lit tests still fail.)

See FIXME in diff for details.

Part of PR43592.

Sam McCall 915f9785e0 [clangd] Rename ClangdUnit.h -> ParsedAST.h. NFC
This much better reflects what is (now) in this header.
Maybe a rename to ParsedTU would be an improvement, but that's a much
more invasive change and life is too short.

ClangdUnit is dead, long live ClangdUnitTests!

Ilya Biryukov 56bdb0c508 [clangd] Compute scopes eagerly in IncludeFixer
Summary:
Computing lazily leads to crashes. In particular, computing scopes may
produce diagnostics (from inside template instantiations) and we
currently do it when processing another diagnostic, which leads to
crashes.

Moreover, we remember and access 'Scope*' when computing scopes. This
might lead to invalid memory access if the Scope is deleted by the time
we run the delayed computation. We did not actually construct an example
when this happens, though.

From the VCS and review history, it seems the optimization was
introduced in the initial version without a mention of any performance
benchmarks justifying the performance gains. This led me to a
conclusion that the optimization was premature, so removing it to avoid
crashes seems like the right trade-off at that point.

Kadir Cetinkaya 38496d5bd9 [clangd] Ignore diags from builtin files
Summary:
This fixes a case where we show diagnostics on arbitrary lines, in an
internal codebase.

Open for ideas on unittesting this.

Haojian Wu ee08036df8 [clangd] Deduplicate clang-tidy diagnostic messages.
Summary:
Clang-tidy checks may emit duplicated messages (clang-tidy tool
deduplicate them in its custom diagnostic consumer), and we may show
multiple duplicated diagnostics in the UI, which is really bad.

This patch makes clangd do the deduplication, and revert the change
rL363889.

Haojian Wu b739b91cd3 [clangd] Make FixIt message be consistent with the clang-tidy diagnostic message.
Summary:
We strip the "[clang-tidy-check]" suffix from the clang-tidy diagnostics, we
should be consistent with the message in FixIt (strip the suffix as well).

Sam McCall b804eef090 [clangd] Move clangd tests to clangd directory. check-clangd is no longer part of check-clang-tools.
Summary:
Motivation:
 - this layout is a pain to work with
 - without a common root, it's painful to express things like "disable clangd" (D61122)
 - CMake/lit configs are a maintenance hazard, and the more the one-off hacks
   for various tools are entangled, the more we see apathy and non-ownership.

This attempts to use the bare-minimum configuration needed (while still
supporting the difficult cases: windows, standalone clang build, dynamic libs).
In particular the lit.cfg.py and lit.site.cfg.py.in are merged into lit.cfg.in.
The logic in these files is now minimal.

(Much of clang-tools-extra's lit configs can probably be cleaned up by reusing
lit.llvm.llvm_config.use_clang(), and every llvm project does its own version of
LDPATH mangling. I haven't attempted to fix any of those).

Docs are still in clang-tools-extra/docs, I don't have any plans to touch those.
