trivial.
We previously took a shortcut by assuming that if a subobject had a
trivial copy assignment operator (with a few side-conditions), we would
always invoke it, and could avoid going through overload resolution.
That turns out to not be correct in the presenve of ref-qualifiers (and
also won't be the case for copy-assignments with requires-clauses
either). Use the same logic for lazy declaration of copy-assignments
that we use for all other special member functions.
Summary:
The unittest for AST matchers has its own way to specify language
standards. I unified it with the shared infrastructure from
libClangTesting.

Summary:
The syntax tree test uses a helper function that executes all testing
assertions. When an assertion fails, the only line number that gets
printed to the log refers to the helper function. After this change, we
would also get the line number of the EXPECT_TRUE macro invocation
(unfortunately, the line number of the last token of it, not the first
one, but there's not much I can do about it).

Summary:
I think we would be better off with tests explicitly specifying the
language mode. Right now Lang_C means C99, but reads as "any C version",
or as "unspecified C version".
I also changed '-std=c++98' to '-std=c++03' because they are aliases (so
there is no difference in practice), because Clang implements C++03
rules in practice, and because 03 makes a nice sortable progression
between 03, 11, 14, 17, 20.

I have seen this myself many times.. if you have format on save and you work in an editor where you are constantly saving (:w muscle memory)
If you are in the middle of editing and somehow you've missed a { or } in your code, somewhere, often way below where you are at the bottom of your file the namespace comment fixer will have put the namespace on the previous closing brace.
This leads to you having to fix up the bottom of the file.
This revision prevents that happening by performing an initial pass of the tokens and simply counting the number of `{` and `}` and ensuring they balance.
If they don't balance we don't do any namespace fixing as it will likely be unstable and incorrect.

Summary:
Declaring these helpers in the ast_matcher namespace in the clangAST
unit test seems inappropriate -- neither these helpers, nor clangAST have
anything to do with AST matchers. Therefore, I moved these helpers to
the clang namespace.
Declaring another typedef called "ArgVector" is not a good idea -- we
already have both "ArgVector", "ArgsVector", and "ArgList". I expanded
it into the underlying type.
Declaring another enum called "Language" is not a good idea because we
arleady have the "clang::Language" enum. I renamed it to
"TestLanguage".
Similarly, I renamed "getBasicRunOptionsForLanguage" to
"getCommandLineArgsForTesting" to explain the semantics better (what are
"run options"?) and not repeat types in the function name
("ForLanguage").

Summary:
Currently, all changes returned by a single application of a rule must fit in
one atomic change and therefore must apply to one file. However, there are
patterns in which a single rule will want to modify multiple files; for example,
a header and implementation to change a declaration and its definition. This
patch relaxes Transformer, libTooling's interpreter of RewriteRules, to support
multiple changes.

Improved safety of RangeSet::Intersect function. Added isEmpty() check to prevent an assertion.
Added support of handling unsigned ranges to RangeSet::Negate and RangeSet::getRangeForMinusSymbol.
Extended RangeSet::getRangeForMinusSymbol to return not only range sets with single value [n,n], but with wide ranges [n,m].
Added unit test for Negate function.

Summary:
The following revision follows D80115 since @MyDeveloperDay and I apparently both had the same idea at the same time, for https://bugs.llvm.org/show_bug.cgi?id=45816 and my efforts on tooling support for AMDVLK, respectively.
This option aligns adjacent bitfield separators across lines, in a manner similar to AlignConsecutiveAssignments and friends.
Example:
```
struct RawFloat {
uint32_t sign : 1;
uint32_t exponent : 8;
uint32_t mantissa : 23;
};
```
would become
```
struct RawFloat {
uint32_t sign : 1;
uint32_t exponent : 8;
uint32_t mantissa : 23;
};
```
This also handles c++2a style bitfield-initializers with AlignConsecutiveAssignments.
```
struct RawFloat {
uint32_t sign : 1 = 0;
uint32_t exponent : 8 = 127;
uint32_t mantissa : 23 = 0;
}; // defaults to 1.0f
```
Things this change does not do:
- Align multiple comma-chained bitfield variables. None of the other
AlignConsecutive* options seem to implement that either.
- Detect bitfields that have a width specified with something other
than a numeric literal (ie, `int a : SOME_MACRO;`). That'd be fairly
difficult to parse and is rare.

https://bugs.llvm.org/show_bug.cgi?id=43845
When a '//comment' trails a consecutive alignment, it adds a whitespace
replacement within the comment token. This wasn't handled correctly in
the alignment code, which treats it as a whole token and thus double
counts it.
This can wrongly trigger the "line too long, it'll wrap" alignment-break
condition with specific lengths, causing the alignment to break for
seemingly no reason.
