hadrian: Compile UserSettings with -O0

This guarantees that the interface file for `UserSettings` doesn't 
contain any unfoldings, ensuring that a change in it requires minimal 
rebuilds.

Make sure mkSplitUniqSupply stores the precomputed mask only.

mkSplitUniqSupply was lazy on the boxed char.

This caused a bunch of issues:
* The closure captured the boxed Char
* The mask was recomputed on every split of the supply.
* It also caused the allocation of MkSplitSupply to happen in it's own
(allocated) closure. The reason of which I did not further investigate.

We know force the computation of the mask inside mkSplitUniqSupply.
* This way the mask is computed at most once per UniqSupply creation.
* It allows ww to kick in, causing the closure to retain the unboxed
value.

Requesting Uniques in a loop is now faster by about 20%.

I did not check the impact on the overall compiler, but I added a test
to avoid regressions.

ghci: Don't rely on resolution of System.IO to base module

Previously we would hackily evaluate a textual code snippet to compute
actions to disable I/O buffering and flush the stdout/stderr handles.
This broke in a number of ways (#15336, #16563).

Instead we now ship a module (`GHC.GHCi.Helpers`) with `base` containing
the needed actions. We can then easily refer to these via `Orig` names.
