For a long time GHC has had some internal mechanism designed to support a call-site inline directive, thus inline f xs makes f be inlined at the call site even if f is big. However, the surface syntax seems to have gone, and in any case it can be done more neatly using a RULE. This commit: * Removes the InlineCall constructor for Note and InlinePlease for SimplCont * Adds a new known-key Id called 'inline', whose definition in GHC.Base is just the identity function * Adds a built-in RULE in PrelRules that rewrites (inline f) to the body of f, if possible * Adds documentation NOTE: I have not tested this (aeroplane work). Give it a try!
