  Log Message:
  -----------
  [clang-tidy] New checker performance-trivially-destructible-check

Checks for types which can be made trivially-destructible by removing
out-of-line defaulted destructor declarations.

The check is motivated by the work on C++ garbage collector in Blink
(rendering engine for Chrome), which strives to minimize destructors and
improve runtime of sweeping phase.

In the entire chromium codebase the check hits over 2000 times.
