[Bug c/87615] Possible excessive compile time with -O2

--- Comment #3 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
On gcc-8 -fno-ipa-cp does not affect time, I brought it up prematurely:

-O2 -time
# cc1 207.15 0.22
-O2 -time -fno-ipa-cp
# cc1 207.57 0.18
-O2 -time -fno-inline
# cc1 21.13 0.10

Looks like gcc-9 regressed here.
