<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Parser.y: clarify treatment of @{-# UNPACK #-}
Before this patch, we had this parser production:
ftype : ...
| ftype PREFIX_AT tyarg { ... }
And 'tyarg' is defined as follows:
tyarg : atype { ... }
| unpackedness atype { ... }
So one might get the (false) impression that that parser production is
intended to parse things like:
F @{-# UNPACK #-} X
However, the lexer wouldn't produce PREFIX_AT followed by 'unpackedness',
as the '@' operator followed by '{-' is not considered prefix.
Thus there's no point using 'tyarg' after PREFIX_AT,
and a simple 'atype' will suffice:
ftype : ...
| ftype PREFIX_AT atype { ... }
This change has no user-facing consequences. It just makes the grammar a
bit more clear.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Introduce OutputableP
Some types need a Platform value to be pretty-printed: CLabel, Cmm
types, instructions, etc.
Before this patch they had an Outputable instance and the Platform value
was obtained via sdocWithDynFlags. It meant that the *renderer* of the
SDoc was responsible of passing the appropriate Platform value (e.g. via
the DynFlags given to showSDoc). It put the burden of passing the
Platform value on the renderer while the generator of the SDoc knows the
Platform it is generating the SDoc for and there is no point passing a
different Platform at rendering time.
With this patch, we introduce a new OutputableP class:
class OutputableP a where
pdoc :: Platform -> a -> SDoc
With this class we still have some polymorphism as we have with `ppr`
(i.e. we can use `pdoc` on a variety of types instead of having a
dedicated `pprXXX` function for each XXX type).
One step closer removing `sdocWithDynFlags` (#10143) and supporting
several platforms (#14335).
