[clang-tools-extra] Fixed a number of typos
I went over the output of the following mess of a command:

`(ulimit -m 2000000; ulimit -v 2000000; git ls-files -z | parallel --xargs -0 cat | aspell list --mode=none --ignore-case | grep -E '^[A-Za-z][a-z]*$' | sort | uniq -c | sort -n | grep -vE '.{25}' | aspell pipe -W3 | grep : | cut -d' ' -f2 | less)`

and proceeded to spend a few days looking at it to find probable typos
and fixed a few hundred of them in all of the llvm project (note, the
ones I found are not anywhere near all of them, but it seems like a
good start).

Haojian Wu 6ba1b9075d Reland "[AST] Add a new TemplateKind for template decls found via a using decl.""
This is the template version of https://reviews.llvm.org/D114251.

This patch introduces a new template name kind (UsingTemplateName). The
UsingTemplateName stores the found using-shadow decl (and underlying
template can be retrieved from the using-shadow decl). With the new
template name, we can be able to find the using decl that a template
typeloc (e.g. TemplateSpecializationTypeLoc) found its underlying template,
which is useful for tooling use cases (include cleaner etc).

This patch merely focuses on adding the node to the AST.

Next steps:
- support using-decl in qualified template name;
- update the clangd and other tools to use this new node;
- add ast matchers for matching different kinds of template names;

Haojian Wu 95f0f69f1f Revert "[AST] Add a new TemplateKind for template decls found via a using decl."
It breaks arm build, there is no free bit for the extra
UsingShadowDecl in TemplateName::StorageType.

Reverting it to build the buildbot back until we comeup with a fix.

This reverts commit 5a5be4044f.

Sam McCall 4d006520b8 [clangd] Clean up unused includes. NFCI
Add includes where needed to fix build.
Haven't systematically added used headers, so there is still accidental
dependency on transitive includes.

David Blaikie 5fb3f43778 Fully qualify template template parameters when printing
I discovered this quirk when working on some DWARF - AST printing prints
type template parameters fully qualified, but printed template template
parameters the way they were written syntactically, or wholely
unqualified - instead, we should print them consistently with the way we
print type template parameters: fully qualified.

The one place this got weird was for partial specializations like in
ast-print-temp-class.cpp - hence the need for checking for
TemplateNameDependenceScope::DependentInstantiation template template
parameters. (not 100% sure that's the right solution to that, though -
open to ideas)

Sam McCall 6aca6032c5 [AST] Include the TranslationUnitDecl when traversing with TraversalScope
Given `int foo, bar;`, TraverseAST reveals this tree:
  TranslationUnitDecl
   - foo
   - bar

Before this patch, with the TraversalScope set to {foo}, TraverseAST yields:
  foo

After this patch it yields:
  TranslationUnitDecl
  - foo

Also, TraverseDecl(TranslationUnitDecl) now respects the traversal scope.

---

The main effect of this today is that clang-tidy checks that match the
translationUnitDecl(), either in order to traverse it or check
parentage, should work.

Simon Pilgrim 61cdaf66fe [ADT] Remove APInt/APSInt toString() std::string variants
<string> is currently the highest impact header in a clang+llvm build:

https://commondatastorage.googleapis.com/chromium-browser-clang/llvm-include-analysis.html

One of the most common places this is being included is the APInt.h header, which needs it for an old toString() implementation that returns std::string - an inefficient method compared to the SmallString versions that it actually wraps.

This patch replaces these APInt/APSInt methods with a pair of llvm::toString() helpers inside StringExtras.h, adjusts users accordingly and removes the <string> from APInt.h - I was hoping that more of these users could be converted to use the SmallString methods, but it appears that most end up creating a std::string anyhow. I avoided trying to use the raw_ostream << operators as well as I didn't want to lose having the integer radix explicit in the code.

Combined with 'da98651 - Revert "DR2064:

Sam McCall 8adc4d1ec7 [clangd] Add textDocument/ast extension method to dump the AST
This is a mass-market version of the "dump AST" tweak we have behind
-hidden-features.
I think in this friendlier form it'll be useful for people outside clang
developers, which would justify making it a real feature.
It could be useful as a step towards lightweight clang-AST tooling in clangd
itself (like matcher-based search).

Advantages over the tweak:
 - simplified information makes it more accessible, likely somewhat useful
   without learning too much clang internals
 - can be shown in a tree view
 - structured information gives some options for presentation (e.g.
   icon + two text colors + tooltip in vscode)
 - clickable nodes jump to the corresponding code
Disadvantages:
 - a bunch of code to handle different node types
 - likely missing some important info vs dump-ast due to brevity/oversight
 - may end up chasing/maintaining support for the long tail of nodes
