Sam McCall 9fb22b2c86 [clangd] Boost code completion results that were named in the last few lines.
Summary:
The hope is this will catch a few patterns with repetition:

  SomeClass* S = ^SomeClass::Create()

  int getFrobnicator() { return ^frobnicator_; }

  // discard the factory, it's no longer valid.
  ^MyFactory.reset();

Without triggering antipatterns too often:

  return Point(x.first, x.^second);

I'm going to gather some data on whether this turns out to be a win overall.

Sam McCall ec026532d6 [clangd] Fix header-guard check for include insertion, and don't index header guards.
Summary:
Both of these attempt to check whether a header guard exists while parsing the
file. However the file is only marked as guarded once clang finishes processing
it. We defer the checks and work until SymbolCollector::finish().

This is ugly and ad-hoc, deferring *all* work might be cleaner.

Sam McCall 15b89df9da [clangd] Improvements to header mapping: more precise parsing of cppreference symbol pages.
Summary:
Previously we were just jumping from the symbol index to the symbol page, and
grabbing all the headers mentioned there. But the page often lists multiple
symbols, and so we got false positives and thus ambiguities (which were dropped).

Now we look at which declarations are for the symbol we want, and prefer headers
listed above that symbol. If there are none, we fall back to the old behavior.

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.

Summary:

This comes at the cost of uniformity, it's no longer totally obvious
exactly what the code field contains. But the -Wname flags are so much
more useful to end-users than the internal warn_foo that this seems worth it.

Sam McCall a96efb654e [clangd] Recognize "don't include me directly" pattern, and suppress include insertion.
Summary:
Typically used with umbrella headers, e.g. GTK:

 #if !defined (__GTK_H_INSIDE__) && !defined (GTK_COMPILATION)
 #error "Only <gtk/gtk.h> can be included directly."
 #endif

Heuristic is fairly conservative, a quick code search over github showed
a fair number of hits and few/no false positives. (Not all were umbrella
headers, but I'd be happy avoiding include insertion for all of them).

We may want to relax the heuristic later to catch more cases.

Sam McCall 62e2472321 [clangd] Include insertion: require header guards, drop other heuristics, treat .def like .inc.
Summary:
We do have some reports of include insertion behaving badly in some
codebases. Requiring header guards both makes sense in principle, and is
likely to disable this "nice-to-have" feature in codebases where headers don't
follow the expected pattern.

With this we can drop some other heuristics, such as looking at file
extensions to detect known non-headers - implementation files have no guards.

One wrinkle here is #import - objc headers may not have guards because
they're intended to be used via #import. If the header is the main file
or is #included, we won't collect locations - merge should take care of
this if we see the file #imported somewhere. Seems likely to be OK.

Headers which have a canonicalization (stdlib, IWYU) are exempt from this check.
*.inc files continue to be handled by looking up to the including file.
This patch also adds *.def here - tablegen wants this pattern too.

In terms of code structure, the division between SymbolCollector and
CanonicalIncludes has shifted: SymbolCollector is responsible for more.
This is because SymbolCollector has all the SourceManager/HeaderSearch access
needed for checking for guards, and we interleave these checks with the *.def
checks in a loop (potentially).
We could hand all the info into CanonicalIncludes and put the logic there
if that's preferable.
