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.
