Apparently I currently can't use -Og when comparing benchmarks of older
Emacsen with Emacs 28 ones because the former don't use static inlines.
I just wanted to know whether -O0 builds of Emacs 28 are also affected
by Paul's change because it's those I use for debugging. Neither -O0
nor -Og builds are useful for normal editing here.
