<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Do absence analysis on stable unfoldings
Ticket #18638 showed that Very Bad Things happen if we fail
to do absence analysis on stable unfoldings. It's all described
in Note [Absence analysis for stable unfoldings and RULES].
I'm a bit surprised this hasn't bitten us before. Fortunately
the fix is pretty simple.

<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.
