[PATCH] Trim MD results to live registers

Subject: [PATCH] Trim MD results to live registers

This is the patch I sent a few days ago to fix PR41812 properly and without introducing memory-usage regressions. It reverts the MD problem to the way it was committed in the first place last June, and fixes PR/41812 in fwprop.

Bootstrapped/regtested x86_64-pc-linux-gnu, with no regressions now that I fixed the bug it exposed in dataflow.

Ok?

Paolo
