Implements an HTML generator.
Nodes are used to represent each part of the HTML file. There are TagNodes that
represent every HTML tag (p, h1, div, ...) and they have children nodes, which
can be TagNodes or TextNodes (these nodes only have text).
Proper indentation is rendered within the files generated by tool.
No styling (CSS) is included.

This moves Bitcode/Bitstream*, Bitcode/BitCodes.h to Bitstream/.
This is needed to avoid a circular dependency when using the bitstream
code for parsing optimization remarks.
Since Bitcode uses Core for the IR part:
libLLVMRemarks -> Bitcode -> Core
and Core uses libLLVMRemarks to generate remarks (see
IR/RemarkStreamer.cpp):
Core -> libLLVMRemarks
we need to separate the Bitstream and Bitcode part.
For clang-doc, it seems that it doesn't need the whole bitcode layer, so
I updated the CMake to only use the bitstream part.

Summary: Tidy check behavior often depends on language and/or clang-tidy options. This revision allows a user of TranformerClangTidyCheck to pass rule _generator_ in place of a rule, where the generator takes both the language and clang-tidy options. Additionally, the generator returns an `Optional` to allow for the case where the check is deemed irrelevant/disable based on those options.

Summary:
Currently, `clang::tidy::test::runCheckOnCode()` constructs the check
instances *before* initializing the ClangTidyContext. This ordering causes
problems when the check's constructor accesses the context, for example, through
`getLangOpts()`.
This revision moves the construction to after the context initialization, which
follows the pattern used in the clang tidy tool itself.

In serialize::parseBases(...), when a base record is a template
specialization, the specialization was used as the parent. It should be
the base template so there is only one file generated for this record.
When the specialized template is implicitly declared the reference USR
corresponded to the GlobalNamespace's USR, this will now be the base
template's USR.
More information about templates will be added later.
In serialize::emiInfo(RecorDecl*, ...), typedef records were not handled
and the name was empty. This is now handled and a IsTypeDef attribute is
added to RecordInfo struct.
In serialize::emitInfo(CXXMethodDecl*, ...), template specialization is
handled like in serialize::parseBases(...).
Bitcode writer and reader are modified to handle the new attribute of

Summary:
In general, the `Explanation` field is optional in `RewriteRule` cases. But,
because the primary purpose of clang-tidy checks is to provide users with
diagnostics, we assume that a missing explanation is a bug. This change adds an
assertion that checks all cases for an explanation, and updates the code to rely
on that assertion correspondingly.

public:
MyTidyCheck(StringRef Name, ClangTidyContext *Context)

unchanged.
Used new version of rename_check.py to make the change in existing
llvm checkers, but had to fix LLVMTidyModule.cpp and
LLVMModuleTest.cpp by hand.
The changes made by rename_check.py are idempotent, so if accidentally
run multiple times, it won't do anything.

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:
- for warnings, use the flag the warning is controlled by (-Wfoo)
- for errors, keep using the internal name (there's nothing better) but
drop the err_ prefix
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.

Typically used with umbrella headers, e.g. GTK:

#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.

Summary:
Motivation/Context: in the code review system integrating with clang-tidy,
clang-tidy doesn't provide a human-readable description of the fix. Usually
developers have to preview a code diff (before vs after apply the fix) to
understand what the fix does before applying a fix.
This patch proposes that each clang-tidy check provides a short and
actional fix description that can be shown in the UI, so that users can know
what the fix does without previewing diff.
This patch extends clang-tidy framework to support fix descriptions (will add implementations for
existing checks in the future). Fix descriptions and fixes are emitted via diagnostic::Note (rather than
attaching the main warning diagnostic).
Before this patch:
```
void MyCheck::check(...) {
...
diag(loc, "my check warning") << FixtItHint::CreateReplacement(...);
}
```
After:
```
void MyCheck::check(...) {
...
diag(loc, "my check warning"); // Emit a check warning
diag(loc, "fix description", DiagnosticIDs::Note) << FixtItHint::CreateReplacement(...); // Emit a diagnostic note and a fix
}

Differential Revision: https://reviews.llvm.org/D59932
llvm-svn: 358576
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.
