Felix Berger adfdc14832 [clang-tidy] Extend UnnecessaryCopyInitialization check to trigger on non-const copies that can be safely converted to const references.
Summary:
Move code shared between UnnecessaryCopyInitialization and ForRangeCopyCheck into utilities files.
Add more test cases for UnnecessaryCopyInitialization and disable fixes inside of macros.

Alexander Kornienko b959f4c338 [clang-tidy] Add UnnecessaryCopyInitialization check to new "performance" module in ClangTidy
Summary:
The patch adds a new ClangTidy check that detects when expensive-to-copy types are unnecessarily copy initialized from a const reference that has the same or are larger scope than the copy.

It currently only detects this when the copied variable is const qualified. But this will be extended to non const variables if they are only used in a const fashion.

Aaron Ballman fc4e042bf5 Improved the misc-move-constructor-init check to identify arguments that are passed by value but copy assigned to class data members when the non-deleted move constructor is a better fit.

Alexander Kornienko 5f252cac51 [clang-tidy] Move IncludeSorter.* and IncludeInserter.* to clang-tidy/utils/
This is better structurally and it also fixes a linker error in the configure
build.

Benjamin Kramer 498cce575f [clang-tidy] Add a generic header guard checker + LLVM implementation.
The implementation is split into a generic part and a LLVM-specific part.
Other codebases can implement it with their own style. The specific features
supported are:

- Verification (and fixing) of header guards against a style based on the file path
- Automatic insertion of header guards for headers that are missing them
- A warning when the header guard doesn't enable our fancy header guard optimization
(e.g. when there's an include preceeding the guard)
- Automatic insertion of a comment with the guard name after #endif.

For the LLVM style we disable #endif comments for now, they're not very common
in the codebase. We also only flag headers in the include directories, there
doesn't seem to be a common style outside.
