[clang-tidy]: new check for "throw by value, catch by reference" guideline

[Tobias Langner]

Hello,

I’d like to submit a new clang-tidy check for review. It tests throw-locations whether objects where thrown by value (and not by pointer) and tests catch-locations whether they catch by const reference. This rule is found in many advice books as guideline. Could someone please review it?

Regards
Tobias
