If you could check, that would be helpful.

Yes.

The time seems to be spent in this function, which has an optimize
declaration of (debug 3) (speed 1); (debug 3) in SBCL means munging
the code substantially, making it very large -- and the function is
large to begin with -- and there are algorithms in the compiler which
are asymptotically slower than O(n).

For what it's worth, the compiler seems to spend its time in
SB-C::PROPAGATE-LIVE-TNS called from SB-C::LIFETIME-FLOW-ANALYSIS.  I
don't know if this has changed recently, but I don't think it has.
