Implement -Woperator-whitespace (#18834)
This patch implements two related warnings:
-Woperator-whitespace-ext-conflict
warns on uses of infix operators that would be parsed
differently were a particular GHC extension enabled
-Woperator-whitespace
warns on prefix, suffix, and tight infix uses of infix
operators
Updates submodules: haddock, containers.
