<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Bump exceptions submodule so that dist-boot is .gitignore'd
`exceptions` is a stage-0 boot library as of commit
30272412fa437ab8e7a8035db94a278e10513413, which means that building
`exceptions` in a GHC tree will generate a `dist-boot` directory.
However, this directory was not specified in `exceptions`'
`.gitignore` file, which causes it to dirty up the current `git`
working directory.
Accordingly, this bumps the `exceptions` submodule to commit
ghc/packages/exceptions@23c0b8a50d7592af37ca09beeec16b93080df98f,
which adds `dist-boot` to the `.gitignore` file.

This patch allows boot libraries to use unboxed sums without implicitly
depending on `base` package because of `absentSumFieldError`.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts: Make non-existent linker search path merely a warning
As noted in #18105, previously this resulted in a rather intrusive error
message. This is in contrast to the general expectation that search
paths are merely places to look, not places that must exist.
Fixes #18105.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Factor out HsPatSigType for pat sigs/RULE term sigs (#16762)
This implements chunks (2) and (3) of
https://gitlab.haskell.org/ghc/ghc/issues/16762#note_270170. Namely,
it introduces a dedicated `HsPatSigType` AST type, which represents
the types that can appear in pattern signatures and term-level `RULE`
binders. Previously, these were represented with `LHsSigWcType`.
Although `LHsSigWcType` is isomorphic to `HsPatSigType`, the intended
semantics of the two types are slightly different, as evidenced by
the fact that they have different code paths in the renamer and
typechecker.
See also the new `Note [Pattern signature binders and scoping]` in
`GHC.Hs.Types`.
