Summary:
The patch adds a new feature for renaming qualified symbol references.
Unlike orginal clang-rename behavior, when renaming a qualified symbol to a new
qualified symbol (e.g "A::Foo" => "B::Bar"), this new rename behavior will
consider the prefix qualifiers of the symbol, and calculate the new prefix
qualifiers. It aims to add as few additional qualifiers as possible.
As this is an early version (only supports renaming classes), I don't change
current clang-rename interfaces at the moment, and would like to keep its
(command-line tool) behavior. So I added new interfaces for the prototype.
In the long run, these interfaces should be unified.
No functionality changes in original clang-rename command-line tool.
This patch also contains a few bug fixes of clang-rename which are discovered by
the new unittest:
* fix a potential nullptr accessment when class declaration doesn't have definition.
* add USRs of nested declartaions in "getNamedDeclFor".

llvm-svn: 298607
Summary:
Using CaseType::CT_AnyCase for selected identifier results in inheriting case style setting from more basic identifier type.
This patch changes CT_AnyCase behavior to ignore case style of specified identifier. If case style was not set, llvm::Optional will be used for keeping this information (llvm::Optional<>::hasVal), thus CT_AnyCase will no longer mean more general identifier style should be used.
This eliminates false-positives when naming convention is not clear for specific areas of code (legacy, third party) or for selected types.

ADL as reasonable extension points.
All of this would be cleaner if this code followed the more usual LLVM
convention of not having deeply nested namespaces inside of .cpp files
and instead having a `using namespace ...;` at the top. Then the static
function would be in the global namespace and easily referred to as
`::join`. Instead we have to write a fairly contrived qualified name.
I figure the authors can clean this up with a less ambiguous name, using
the newly provided LLVM `join` function, or any other solution, but this
at least fixes the build.
llvm-svn: 298434
Summary:
When changing namespaces, the tool adds leading "::" to references that need to
be fully-qualified, which would affect readability.
We avoid adding "::" when the symbol name does not conflict with the new
namespace name. For example, a symbol name "na::nb::X" conflicts with "ns::na"
since it would be resolved to "ns::na::nb::X" in the new namespace.

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).
