restore -fmax-worker-args handling (Trac #11565)
maxWorkerArgs handling was accidentally lost 3 years ago
in a major update of demand analysis
commit 0831a12ea2fc73c33652eeec1adc79fa19700578
Old regression is noticeable as:
- code bloat (requires stack reshuffling)
- compilation slowdown (more code to optimise/generate)
- and increased heap usage (DynFlags unboxing/reboxing?)
On a simple compile benchmark this change causes heap
allocation drop from 70G don to 67G (ghc perf build).
