Comment (by tdammers):

 I tried a plain old stage2 build, comparing GHC HEAD against a version
 with added `NOINLINE` on `make_ord_flag` and `make_dep_flag`, which seems
 to reduce compile times only marginally, and overall memory use from 72M
 to 70M.

 Anything else that you think might benefit from `NOINLINE`?
