<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Care with occCheckExpand in kind of occurrences
Issue #18451 showed that we could get an infinite type, through
over-use of occCheckExpand in the kind of an /occurrence/ of a
type variable.
See Note [Occurrence checking: look inside kinds] in GHC.Core.Type
This patch fixes the problem by making occCheckExpand less eager
to expand synonyms in kinds.
It also improves pretty printing of kinds, by *not* suppressing
the kind on a tyvar-binder like
(a :: Const Type b)
where type Const p q = p. Even though the kind of 'a' is Type,
we don't want to suppress the kind ascription. Example: the
error message for polykinds/T18451{a,b}. See GHC.Core.TyCo.Ppr
Note [Suppressing * kinds].

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Remove platform constant wrappers
Platform constant wrappers took a DynFlags parameter, hence implicitly
used the target platform constants. We removed them to allow support
for several platforms at once (#14335) and to avoid having to pass
the full DynFlags to every function (#17957).
Metric Decrease:

Previously it was in ghc-boot so that ghc-pkg could use it. However it
wasn't necessary because ghc-pkg only uses a subset of it: reading
target arch and OS from the settings file. This is now done via
GHC.Platform.ArchOS (was called PlatformMini before).
