[cfe-dev] Removing Clang-modernize

[Eugene Zelenko via cfe-dev]

Hi!

I think will be good idea to remove Clang-modernize at least from
installation if not from build or even source tree before 3.8 release.

Functionality was moved to Clang-tidy already. Old conversions were
improved and new conversions was added in Clang-tidy.

So Clang-modernize only takes space and build time without providing
any advantages over Clang-tidy.

Eugene.
