DmdAnal: Turn `LP(A)` into `LP(L)` in signatures (#19407)wip/T19407
This patch fixes some abundant reboxing of `DynFlags` in
`GHC.HsToCore.Match.Literal.warnAboutOverflowedLit` with a justifiable hack.
See the new `Note [Turn LP(A) into LP(M) in signatures]` and the new regression
test `T19407`.
There is a +4% ghc/alloc metric increase in T12545. The baseline is 1.7GB, this
patch uses 1.76GB. But if I pass `-v` then suddenly the baseline takes 1.8GB, this
patch 1.78GB. So it's actually an improvement! It appears that this patch is
somehow a bit more strict. In fact, in other jobs the same metric decreases.
Tracked as #19801.
