Compiling ghc with `-fmax-worker-args=20` causes absentError panic.
Using `stage1.*.ghc.hs.opts += -fmax-worker-args=20` and `hadrian/build -j2 -o_max20` the resulting executable panics with this error:
```
andi@horzube:~/ghc_head$ _max20/stage1/bin/ghc nofib/spectral/simple/Main.hs -O -fforce-recomp -c
ghc: internal error: Oops! Entered absent arg Arg: ww
Type: Bool
In module `GHC.Tc.Utils.Monad'
(GHC version 9.5.20220502 for x86_64_unknown_linux)
Please report this as a GHC bug: https://www.haskell.org/ghc/reportabug
Aborted (core dumped)
```
Likely a bug in W/W or demand analysis.
