[PATCH] D52727: [clang-tidy] White List Option for performance-unnecessary-value-param, performance-unnecessary-copy-initialization and performance-for-range-copy

baloghadamsoftware added a project: clang-tools-extra.

New option added to these three checks to be able to silence false positives on types that are intentionally passed by value or copied. Such types are e.g. intrusive reference counting pointer types like `llvm::IntrusiveRefCntPtr`. The new option is named `WhiteListTypes` and can contain a semicolon-separated list of names of these types. Regular expressions are allowed. Default is empty.
