Introduce IsPass; refactor wrappers.
There are two main payloads of this patch:
1. This introduces IsPass, which allows e.g. printing
code to ask what pass it is running in (Renamed vs
Typechecked) and thus print extension fields. See
Note [IsPass] in Hs.Extension
2. This moves the HsWrap constructor into an extension
field, where it rightly belongs. This is done for
HsExpr and HsCmd, but not for HsPat, which is left
as an exercise for the reader.
There is also some refactoring around SyntaxExprs, but this
is really just incidental.
This patch subsumes !1721 (sorry @chreekat).
Along the way, there is a bit of refactoring in GHC.Hs.Extension,
including the removal of NameOrRdrName in favor of NoGhcTc.
This meant that we had no real need for GHC.Hs.PlaceHolder, so
I got rid of it.
Updates haddock submodule.
