SI-2807 Resurrect and refine the promiscuous catch warning.

The previous incarnation didn't survive 4fb3473.

This version can be cleared by using a typed pattern: `catch { case _: Throwable => }`.

This is motivated by the recent appearance of such a catch in `util.Try`, and by battle
scars left by one too many processes bravely but stupidly catching and logging OutOfMemoryErrors.

-Y status has been skipped: this warning is enabled by default and can only be silenced
with use of a typed pattern.
