Keep track of promotion ticks in HsOpTywip/no-c-stubswip/matt-merge-batch
This patch adds a PromotionFlag field to HsOpTy, which is used
in pretty-printing and when determining whether to emit warnings
with -fwarn-unticked-promoted-constructors.
This allows us to correctly report tick-related warnings for things
like:
type A = Int : '[]
type B = [Int, Bool]
Updates haddock submodule
Fixes #19984
