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 in Chrome), which strives to minimize destructor usage
and improve runtime of sweeping phase.

In the entire chromium codebase the check hits over ~2500 times.
