This patch moves the virtual file system form clang to llvm so it can be
used by more projects.
Concretely the patch:
- Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
- Moves the corresponding unit test from clang to llvm.
- Moves the vfs namespace from clang::vfs to llvm::vfs.
- Formats the lines affected by this change, mostly this is the result of
the added llvm namespace.

We do now both:
- stop reformatting a sequence after a closing brace in more cases, in
order to not misindent after an incorrect closing brace
- format the closing brace when formatting the line containing the
opening brace

We currently use target_link_libraries without an explicit scope
specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables.
Dependencies added in this way apply to both the target and its
dependencies, i.e. they become part of the executable's link interface
and are transitive.
Transitive dependencies generally don't make sense for executables,
since you wouldn't normally be linking against an executable. This also
causes issues for generating install export files when using
LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM
library dependencies, which are currently added as interface
dependencies. If clang is in the distribution components but the LLVM
libraries it depends on aren't (which is a perfectly legitimate use case
if the LLVM libraries are being built static and there are therefore no
run-time dependencies on them), CMake will complain about the LLVM
libraries not being in export set when attempting to generate the
install export file for clang. This is reasonable behavior on CMake's
part, and the right thing is for LLVM's build system to explicitly use
PRIVATE dependencies for executables.
Unfortunately, CMake doesn't allow you to mix and match the keyword and
non-keyword target_link_libraries signatures for a single target; i.e.,
if a single call to target_link_libraries for a particular target uses
one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must
also be updated to use those keywords. This means we must do this change
in a single shot. I also fully expect to have missed some instances; I
tested by enabling all the projects in the monorepo (except dragonegg),
and configuring both with and without shared libraries, on both Darwin
and Linux, but I'm planning to rely on the buildbots for other
configurations (since it should be pretty easy to fix those).
Even after this change, we still have a lot of target_link_libraries
calls that don't specify a scope keyword, mostly for shared libraries.
I'm thinking about addressing those in a follow-up, but that's a
separate change IMO.

Summary:
Add fuzzy SymbolIndex, where identifier needn't match exactly.
The purpose for this is global autocomplete in clangd. The query will be a
partial identifier up to the cursor, and the results will be suggestions.
It's in include-fixer because:
- it handles SymbolInfos, actually SymbolIndex is exactly the right interface
- it's a good harness for lit testing the fuzzy YAML index
- (Laziness: we can't unit test clangd until reorganizing with a tool/ dir)
Other questionable choices:
- FuzzySymbolIndex, which just refines the contract of SymbolIndex. This is
an interface to allow extension to large monorepos (*cough*)
- an always-true safety check that Identifier == Name is removed from
SymbolIndexManager, as it's not true for fuzzy matching
- exposing -db=fuzzyYaml from include-fixer is not a very useful feature, and
a non-orthogonal ui (fuzziness vs data source). -db=fixed is similar though.

Summary:
Remove line number from Symbol identity.
For our purposes (include-fixer and clangd autocomplete), function overloads
within the same header should mostly be treated as a single combined symbol.
We may want to track individual occurrences (line number, full type info)
and aggregate this during mapreduce, but that's not done here.

Summary:
Add usage count to find-all-symbols.
FindAllSymbols now finds (most!) main-file usages of the discovered symbols.
The per-TU map output has NumUses=0 or 1 (only one use per file is counted).
The reducer aggregates these to find the number of files that use a symbol.
The NumOccurrences is now set to 1 in the mapper rather than being inferred by
the reducer, for consistency.
The idea here is to use NumUses for ranking: intuitively number of files that
use a symbol is more meaningful than number of files that include the header.

Summary:
Fix no std::function index.
Previously, we don't index all the template specialization declarations of functions and classes (Because we assume that template functions/classes are indexed by their template declarations), but this is not always true in some cases like `std::function` which only has a partial template specialization declaration.

We don't actually need the index until parse time, so fetch it in the
background and start parsing. By the time it is actually needed it's
likely that the loading phase has completed in the background.

This will look through typedefs so include-fixer will look up the target
of the typedef instead of the typedef itself (which is already in
scope).
llvm-svn: 289952
Summary:
Previously, if we pass multiple files or a file pattern (e.g. /path/to/*.cc) to
include-fixer, include-fixer will apply all replacements to the first argument,
which probably causes crashes.
With this patch, include-fixer can process multiple files now.
Vim and Emacs integration are tested manually.

Summary:
include-fixer will firstly try to use scoped namespace context information to
search identifier. However, in some cases, it's unsafe to do nested class
search, because it might treat the identifier as a nested class of scoped
namespace.
Given the following code, and the symbol database only has two classes: "foo" and
"b::Bar".
namespace foo { Bar t; }
Before getting fixing, include-fixer will never search "Bar" symbol.
Because it firstly tries to search "foo::Bar", there is no "Bar" in foo namespace,
then it finds "foo" in database finally. So it treats "Bar" is a nested class
of "foo".

Summary:
This is an initial version of fixing namespace issues by adding missing
namespace qualifiers to an unidentified symbol.
This version only fixes the first discovered unidentified symbol.
In the long run, include-fixer should fix all unidentified symbols
with a same name at one run.
Currently, it works on command-line tool. The vim integration is not
implemented yet.

Summary:
we should only deduplicate symbols after matching symbols with the
undefined identifier. This patch tries to fix the situation where matching
symbols are deleted when it has the same header as a non-matching symbol, which
can prevent finding the correct header even if there is a matched symbol.

Summary:
Currently, removing dot dot in header's path doesn't make include-fixer
minimize path correctly in some cases, for example, specify a relative search
path based on the build directory("-I../include/").
Besides, removing dot dot can break symbolic link directories. So don't
removing it for now.

This is used to find nested classes. For a nested name foo::bar::qux we
will first look up foo::bar::qux, then foo::bar, then foo unless we find
a result. This is used to support nested classes which are not part of
the index but can only be used if the header for the parent context is
included.
