	SB-EXT:MUFFLE-CONDITIONS.  Go wild.
	... rejig the implementation a bit more from the latest CSR
		sbcl-devel patch: new SB-C::*HANDLED-CONDITIONS*
		variable analogous to SB-C::*POLICY* (and treated with
		the same kinds of hack, too, with rebindings and other
		fakery to get the right semantics);
	... more test cases;
	... documentation;
	... since we're in the general area, make
		SB-CLTL2:DECLARATION-INFORMATION work on it...
	... and write test cases for this and OPTIMIZE.
