<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts: Properly free the RTSSummaryStats structure
`stat_exit` always allocates a `RTSSummaryStats` but only sometimes
frees it, which casues leaks. With this patch we unconditionally free
the structure, fixing the leak.
Fixes #16584

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Hadrian: override $(ghc-config-mk), to prevent redundant config generation
This required making the 'ghc-config-mk' variable overridable in
testsuite/mk/boilerplate.mk, and then making use of this in hadrian
to point to '<build root>/test/ghcconfig' instead, which is where we
always put the test config.
Previously, we would build ghc-config and run it against the
GHC to be tested, a second time, while we're running the tests, because some
include testsuite/mk/boilerplate.mk. This was causing unexpected output
failures.

As of commit d37d91e9a444a7822eef1558198d21511558515e, the GHC build
now autogenerates a `includes/dist/build/settings` file. To avoid
dirtying the current `git` status, this adds `includes/dist` to
`.gitignore`.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Check for duplicate variables in associated default equations
A follow-up to !696's, which attempted to clean up the error messages
for ill formed associated type family default equations. The previous
attempt, !696, forgot to account for the possibility of duplicate
kind variable arguments, as in the following example:
```hs
class C (a :: j) where
type T (a :: j) (b :: k)
type T (a :: k) (b :: k) = k
```
This patch addresses this shortcoming by adding an additional check
for this. Fixes #13971 (hopefully for good this time).

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Make tablesNextToCode a proper dynamic flag (#15548)
Summary:
There is no more use of the TABLES_NEXT_TO_CODE CPP macro in
`compiler/`. GHCI_TABLES_NEXT_TO_CODE is also removed entirely. The
default value of `tablesNextToCode` is calculated as before, but now
users of the GHCI API can modify this flag.
That said, GHC still is hardcoded to define TABLES_NEXT_TO_CODE based on
that default value. This is bad, but neccessary until the remaining uses
of TABLES_NEXT_TO_CODE get it from make/Hadrian.
