<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Properly trim IdInfos of DFunIds and PatSyns in TidyPgm
Not doing this right caused #16608. We now properly trim IdInfos of
DFunIds and PatSyns.
Some further refactoring done by SPJ.
Two regression tests T16608_1 and T16608_2 added.
Fixes #16608

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Add -Winferred-safe-imports warning
This commit partly reverts e69619e923e84ae61a6bb4357f06862264daa94b
commit by reintroducing Sf_SafeInferred SafeHaskellMode.
We preserve whether module was declared or inferred Safe. When
declared-Safe module imports inferred-Safe, we warn. This inferred
status is volatile, often enough it's a happy coincidence, something
which cannot be relied upon. However, explicitly Safe or Trustworthy
packages won't accidentally become Unsafe.
Updates haddock submodule.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix #1620: ModBreaks.modBreaks_array not initialised
After a :cd command and after setting some package flags,
GHCi unloads all loaded modules by resetting the list of targets.
This patch deletes eventually defined debugger breakpoints, before GHCi resets the target list.
The common code is factored out into the new function clearAllTargets.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix two places that failed the substitution invariant
The substition invariant relies on keeping the in-scope
set in sync, and we weren't always doing so, which means that
a DEBUG compiler crashes sometimes with an assertion failure
This patch fixes a couple more cases. Still not validate
clean (with -DEEBUG) but closer!

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix typechecking of partial type signatures
Partial type sigs had grown hair. tcHsParialSigType was
doing lots of unnecessary work, and tcInstSig was cloning it
unnecessarily -- and the result didn't even work: #16728.
This patch cleans it all up, described by TcHsType
Note [Checking parital type signatures]
I basically just deleted code... but very carefully!
Some refactoring along the way
* Distinguish more explicintly between "anonymous" wildcards "_"
and "named" wildcards "_a". I changed the names of a number
of functions to make this distinction much more apparent.
The patch also revealed that the code in `TcExpr`
that implements the special typing rule for `($)` was wrong.
It called `getRuntimeRep` in a situation where where was no
particular reason to suppose that the thing had kind `TYPE r`.
This caused a crash in typecheck/should_run/T10846.
The fix was easy, and actually simplifies the code in `TcExpr`
quite a bit. Hooray.

* Added Note [Quantified varaibles in partial type signatures]
in TcRnTypes
* Kill dVarSetElemsWellScoped; it was only called in
one function, quantifyTyVars. I inlined it because it
was only scopedSort . dVarSetElems
* Kill Type.tyCoVarsOfBindersWellScoped, never called.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Move 'Platform' to ghc-boot
ghc-pkg needs to be aware of platforms so it can figure out which
subdire within the user package db to use. This is admittedly
roundabout, but maybe Cabal could use the same notion of a platform as
GHC to good affect too.
