Same thing for hashes100.c (profile in comment #45 is for infcodes100.c), in
both cases cc1 r155486 at -O2 on x86_64):
Flat profile:

For hashes100.c, combine+IRA+expand+tree-PRE accounts for 1/3 of the total
compile time. For infcodes100.c, the profile is more flat, but IRA+expand still
account for 1/4 of the total compile time.
Why is IRA so
