Imagine a world where you could just hover over any SmallVector and
instantly see a histogram of the maximum sizes it achieves during its
lifetime (compiling, say, the whole test-suite, or a self-host)... I
want that...

Even better, an automated tool that highlights SmallVector's which
regularly overflow or underuse their small storage and should have
their size bumped up or down.
