<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Revert "Specify kind variables for inferred kinds in base."
As noted in !3132, this has rather severe knock-on consequences in
user-code. We'll need to revisit this before merging something along
these lines.
This reverts commit 9749fe1223d182b1f8e7e4f7378df661c509f396.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Coverage: Drop redundant ad-hoc boot module check
To determine whether the module is a boot module
Coverage.addTicksToBinds was checking for a `boot` suffix in the module
source filename. This is quite ad-hoc and shouldn't be necessary; the
callsite in `deSugar` already checks that the module isn't a boot
module.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Add info about typeclass evidence to .hie files
See `testsuite/tests/hiefile/should_run/HieQueries.hs` and
`testsuite/tests/hiefile/should_run/HieQueries.stdout` for an example of this
We add two new fields, `EvidenceVarBind` and `EvidenceVarUse` to the
`ContextInfo` associated with an Identifier. These are associated with the
appropriate identifiers for the evidence variables collected when we come across
`HsWrappers`, `TcEvBinds` and `IPBinds` while traversing the AST.
Instance dictionary and superclass selector dictionaries from `tcg_insts` and
classes defined in `tcg_tcs` are also recorded in the AST as originating from
their definition span
This allows us to save a complete picture of the evidence constructed by the
constraint solver, and will let us report this to the user, enabling features
like going to the instance definition from the invocation of a class method(or
any other method taking a constraint) and finding all usages of a particular
instance.
Additionally,
- Mark NodeInfo with an origin so we can differentiate between bindings
origininating in the source vs those in ghc
- Along with typeclass evidence info, also include information on Implicit
Parameters
- Add a few utility functions to HieUtils in order to query the new info
Updates haddock submodule

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Make WorkWrap.Lib.isWorkerSmallEnough aware of the old arity
We should allow a wrapper with up to 82 parameters when the original
function had 82 parameters to begin with.
I verified that this made no difference on NoFib, but then again
it doesn't use huge records...
Fixes #18122.
