Summary:
This patch fixes [[ https://bugs.llvm.org/show_bug.cgi?id=32896 | PR32896 ]].
The problem was that modernize-use-emplace incorrectly removed changed push_back into emplace_back, removing explicit constructor call with initializer list parameter, resulting in compiler error after applying fixits.
modernize-use-emplace used to check if matched constructor had InitListExpr, but didn't check against CXXStdInitializerListExpr.
Eg.
```
std::vector<std::vector<int>> v;
v.push_back(std::vector<int>({1})); // --> v.emplace_back({1});
```

When there is a push_back with a call to make_pair, turn it into emplace_back and remove the unnecessary make_pair call.
Eg.
```
std::vector<std::pair<int, int>> v;
v.push_back(std::make_pair(1, 2)); // --> v.emplace_back(1, 2);
```
make_pair doesn't get removed when explicit template parameters are provided, because of potential problems with type conversions.

llvm-svn: 301651
Summary:
The goal of this change is to fix the following suboptimal replacements currently suggested by clang-tidy:
```
// with MemberPrefix == "_"
int __foo; // accepted without complaint
```
```
// with MemberPrefix == "m_"
int _foo;
^~~~~~
m__foo
```
I fixed this by
- updating `matchesStyle()` to reject names which have a leading underscore after a prefix has already been stripped, or a trailing underscore if a suffix has already been stripped;
- updating `fixupWithStyle()` to strip leading & trailing underscores before adding the user-defined prefix and suffix.
The replacements are now:
```
// MemberPrefix == "_"
int __foo;
^~~~~~
_foo
```
```
// MemberPrefix == "m_"
int _foo;
^~~~~
m_foo
```
Future improvements might elect to add .clang-tidy flags to improve what is being stripped. For instance, stripping `m_` could allow `m_foo` to be automatically replaced with `_foo`.

Summary:
When running run-clang-tidy.py with -fix it tries to apply found replacements at the end.
If there are errors running clang-apply-replacements, the script currently crashes or displays no error at all.
This patch checks for errors running clang-apply-replacements the same way clang-tidy binary is handled.
Another option would be probably checking for clang-apply-replacements (when -fix is passed) even before running clang-tidy.

textDocument/completion sends a TextDocumentPositionParams message in the 2.x
and 3.x. But in 1.x it was instead a TextDocumentPosition with inlined
parameters. This means that the "uri" field is at the top level and not in
textDocument. Because of this, some clients that maintain compability with 1.x
have both uri and textDocument.uri. Clangd, however, early returns in the
presence of anything but 'textDocument' or 'position' which prevents a client
compatible with both 3.x and 1.x to work correctly. If Clangd was a bit more
permissive (no early return), clients implementing all the versions of the
protocol would work.

Clangd strips URIs by removing the file:// part but some clients can send file:
which is also valid according to RFC 3896. For example, if a client sends
file:///home/user, it gets converted to /home/user but if a client sends
file:/home/user, it is left untouched and problems arise.

Summary:
The "performance-inefficient-vector-operation" check finds vector oprations in
for-loop statements which may cause multiple memory reallocations.
This is the first version, only detects typical for-loop:
```
std::vector<int> v;
for (int i = 0; i < n; ++i) {
v.push_back(i);
}
// or
for (int i = 0; i < v2.size(); ++i) {
v.push_back(v2[i]);
}
```
We can extend it to handle more cases like for-range loop in the future.

rfc8089#appendix-E.2 specifies that paths can begin with a drive letter e.g. as file:///c:/.

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".

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.
