Remove InlinePlease and add inline function and RULE
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!
