Adding something to a SourceLocation will only produce an invalid
SourceLocation in edge cases (overflow or adding 0 to an invalid one).
Check that the offset is inside the file instead and add a test case to
verify that the error message works.

Due to the way the preprocessor works nodes can be half in a macro or a
different file. This means checking the file name of the start location
of a Decl is not a correct way of checking if the entire Decl is in that
file. Remove that flawed assumption and replace it with a more effective
check: If the point we're looking for is *inside* of the begin and end
location of a Decl, look inside.
This should make clang-rename more reliable (for example macro'd namespaces
threw it off before, as seen in the test case) and maybe a little faster
by pruning off more stuff that the RecursiveASTVisitor doesn't have to
drill into.

* Use lexical binding, as recommended for new libraries.
* Fix customization variable (set correct group and type).
* Create a new customization group for the library.
* Autoload the main clang-rename command so that users don't have to explicitly load the library.
* Correctly translate between file and buffer positions using bufferpos-to-filepos (if available) or a fallback.
* Don't invoke the shell, it's not necessary and adds complexity.
* Save clang-rename output in a buffer and display that on failure.
* Save all buffers before calling clang-rename. This is required anyway and prevents data loss when the buffer is later reverted.
* In revert-buffer, use keywords instead of t for Boolean arguments to improve readability.
* Don't reset buffer modes when reverting.
* Emacs treats the character after a symbol as part of the symbol, while clang-rename doesn't; resolve this inconsistency.
* Formatting.

After applying `clang-rename` to a vim buffer (using `clang-rename.py` as part
of the vim integration) the buffer gets reloaded using `bufdo`. This solution is
suboptimal, since syntax highlighting is turned off for performance reasons and
never turned on, after all changes to the source file have been applied.
A better solution to this is using `checktime`. It is exactly designed for this
kind of task and doesn't have the syntax highlighting issue.

Fix the output of clang-rename for the files without modifications.
Update the code in clang-reorder-fields/tool/ClangReorderFields.cpp
to avoid inconsistency.
Example:
a.h:
struct A {};
a.cpp:
#include "a.h"
int main() { return 0; }
Before the changes the output looks like this:
clang-rename -qualified-name=A -new-name=B a.cpp

Having both rename-at and rename-all both seems confusing and introduces
unneeded difficulties. After merging rename-at and rename-all maintaining main
function wrappers and custom help becomes redundant while CLI becomes less
confusing.
D24224 (which was the original patch causing buildbot failures) wasn't aware of
bugs caused by passing both -offset and -qualified-name. After D24224 was landed
it caused buildbot failures and therefor I just reverted it.
Two things that make this patch different from D24224 are:
* unittests/clang-rename was deleted, because it is unmaintained and doesn't do
much.
* Passing both `-offset` and `-qualified-name` isn't allowed anymore for the
sake of preventing bugs.
This patch is a trivial enhancement of accepted D24224 revision.
Tested with `ninja check-all`.

Having both rename-at and rename-all both seems confusing and introduces
unneeded difficulties. Allowing to use both -qualified-name and -offset at once
while performing efficient renamings seems like a feature, too. Maintaining main
function wrappers and custom help becomes redundant while CLI becomes less
confusing.

Although it is not explicitly stated in LLVM Coding Standards, LLVM developers
prefer to omit braces around flow control statements with single line body.
For example the following piece of code
```
if (condition)
std::cout << "Hello, world!" << std::endl;
```
is preferred to
```
if (condition) {
std::cout << "Hello, world!" << std::endl;
}
```
So far clang-rename has ignored this. This patch makes clang-rename more
"LLVM-ish".

As Eric Fiselier pointed out, r278760 breaks build, because RecursiveASTVisitor
doesn't have a const overload. This patch is a quick fix.
llvm-svn: 278780
As Alexander pointed out, LLVM Coding Standards are more conservative about
using auto, i.e. it should be used in the following situations:
* When the type is obvious, i.e. explicitly mentioned in the same expression.
For example `if (const clang::FieldDecl *FieldDecl = Initializer->getMember())`.
* When the type is totally non-obvious and one iterates over something. For
example
`for (const auto &CurrDecl : Context.getTranslationUnitDecl()->decls())`.
Otherwise the type should be explicitly stated.

1. Improve templated class renaming, namely add capabilities of finding partial
and full specializations. Every class partial specialization has reference to
the specialized class. Thus, storing all partial specializations and
comparing specialized class decls to the FoundDecl solves this. All full class
specializations can be found by calling ClassTemplateDecl::specializations().
2. Fix virtual function and its overriding functions renaming. Renaming a
virtual function requires renaming every other function in its "overriding
graph".
3. Merge TemplateClassInstantiationFindBy{Declaration|TypeUse}.cpp tests into
one test by adding multiple invocations of clang-rename to one test, because
the only different thing across these tests is -offset passed to clang-rename.

- rename-at is meant to be integrated with editors and works mainly off
of a location in a file, and this is the default
- rename-all is optimized for one or more oldname->newname renames, and

The complexity of renaming a USR is O(N) [N stands for number of nodes in
Translation Unit]. In some cases there are more than one USR for a single symbol
(see overridden functions and ctor/dtor handling), which means that the
complexity of finding all of the corresponding USRs is O(N * M) [M stands for
number of USRs corresponding to the symbols, which may be not quite small]. With
a simple tweak we can make it O(N * log(M)) by passing whole list of USRs
corresponding to the symbol to USRLocFinder.

Use case: a class is declared in a header, and defined in two
translation units. clang-rename is asked to rename a class member that's
referenced in both translation units.
Using -i is not possible, as in case the first clang-rename invocation
touches the header, the second invocation will result in compilation
errors. Using -export-fixes handles this situation, each invocation can
work on the original source, and at the end the user can apply the
replacements with clang-apply-replacements.
