[Bug ipa/125809] [16/17 Regression] ipa-cp over-clones under a guessed profile: devirtualization_time_bonus frequency-weighting (r16-3990-gad3fb999a1b568) inflates the bonus, ~8% slower cc1 build (SPEC 721.gcc_r)

--- Comment #7 from ptomsich at gcc dot gnu.org ---
Some more experimentation shows that we can't estimate the register pressure
when inlining (working on pre-unroll GIMPLE), as it can't see the post-unroll
register pressure.
