Use the LLVM_UTILS_PROVIDED variable to determine whether test tool
dependencies should be exposed for clang-tools-extra tests. If clang is
being built stand-alone and LLVM test tools (FileCheck, count and not)
are installed, the top-level CMakeLists.txt of clang sets this variable
to indicate that they will not be built as a part of this build,
and therefore no dependencies should be emitted for them. This fixes
the dependency errors when building clang stand-alone with tests
enabled.

Clangd is often waiting for input on getline as it awaits requests. If the
getline is interrupted, it causes the system call (read) to fail and the EINTR
error to be set. This can be seen when attaching a debugger such as LLDB on
macOS. On macOS (and possibly other operating systems), this system call is not
restarted after interruption but on Linux it is restarted which is why
attaching a debugger does work correctly there.
The solution is to work around the non-restarting system call by checking the
errno for EINTR when the stream fails and try again. This should be safe on all
Unixish platforms.
See also http://bugs.llvm.org/show_bug.cgi?id=32149 for some background
discussion.

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:
I've added a test case that (without the fix) triggers the assertion,
which happens when a move happens in an implicitly called conversion
operator.
This patch also fixes nondeterministic behavior in the source code
location reported for the move when the move is constained in an init list;
this was causing buildbot failures in the previous attempt to submit
this patch (see D30569 and rL297004).

Summary:
This uses CodeActions to show 'apply fix' actions when code actions are
requested for a location. The actions themselves make use of a
clangd.applyFix command which has to be implemented on the editor side. I
included an implementation for vscode.
This also adds a -run-synchronously flag which runs everything on the main

Differential Revision: https://reviews.llvm.org/D30002
llvm-svn: 296598
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.

`clang-include-fixer--insert-line` has an off-by-one error because it
uses `(goto-char (point-min)) (forward-char chars)`, which is (goto-char
(1+ chars))`. Because of this, when the first difference was on an empty
line (i.e. an include was appended to the block of includes), the
pointer in the `to` buffer would be on the next line.
Also wrapped calls inside another process sentinel inside `with-local-quit`.

1. Quitting inside a process sentinel is not allowed, but the sentinel invokes
completion, where the user is free to hit C-g. By wrapping the call in
with-local-quit, the process sentinel invocation can finish without triggering
an error
2. Invoke completing-read instead of ido-completing-read, since this may
interfere with user customizations to completing-read-function. The user should
use something like ido-ubiquitous if ido completion is wanted
3. Compare the string returned from completion with string=, since it may be a
copy of the original string in the collection

The check doesn't really know if the code it is warning about came before
or after the header guard, so phrase it more neutral instead of complaining
about code before the header guard. The location for the warning is still
not optimal, but I don't think fixing that is worth the effort, the
preprocessor doesn't give us a better location.

Summary:
This patch adds onTypeFormatting to clangd.
The trigger character is '}' and it works by scanning for the matching '{' and formatting the range in-between.
There are problems with ';' as a trigger character, the cursor position is before the `|`:
```
int main() {
int i;|
}
```
becomes:
```
int main() { int i;| }
```
which is not likely what the user intended.
Also formatting at semicolon in a non-properly closed scope puts the following tokens in the same unwrapped line, which doesn't reformat nicely.

LLVM defines `PTHREAD_LIB` which is used by AddLLVM.cmake and various projects
to correctly link the threading library when needed. Unfortunately
`PTHREAD_LIB` is defined by LLVM's `config-ix.cmake` file which isn't installed
and therefore can't be used when configuring out-of-tree builds. This causes
such builds to fail since `pthread` isn't being correctly linked.
This patch attempts to fix that problem by renaming and exporting
`LLVM_PTHREAD_LIB` as part of`LLVMConfig.cmake`. I renamed `PTHREAD_LIB`
because It seemed likely to cause collisions with downstream users of
`LLVMConfig.cmake`.
