<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Implement cstringLength# and FinalPtr
This function and its accompanying rule resolve issue #5218.
A future PR to the bytestring library will make the internal
Data.ByteString.Internal.unsafePackAddress compute string length
with cstringLength#. This will improve the status quo because it is
eligible for constant folding.
Additionally, introduce a new data constructor to ForeignPtrContents
named FinalPtr. This additional data constructor, when used in the
IsString instance for ByteString, leads to more Core-to-Core
optimization opportunities, fewer runtime allocations, and smaller
binaries.
Also, this commit re-exports all the functions from GHC.CString
(including cstringLength#) in GHC.Exts. It also adds a new test
driver. This test driver is used to perform substring matches on Core
that is dumped after all the simplifier passes. In this commit, it is
used to check that constant folding of cstringLength# works.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">simplCore: Ignore ticks in rule templates
This fixes #17619, where a tick snuck in to the template of a rule,
resulting in a panic during rule matching. The tick in question was
introduced via post-inlining, as discussed in `Note [Simplifying
rules]`. The solution we decided upon was to simply ignore ticks in the
rule template, as discussed in `Note [Tick annotations in RULE
matching]`.
Fixes #18162.
Fixes #17619.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix #18145 and also avoid needless work with implicit vars
- `forAllOrNothing` now is monadic, so we can trace whether we bind
an explicit `forall` or not.
- #18145 arose because the free vars calculation was needlessly
complex. It is now greatly simplified.
- Replaced some other implicit var code with `filterFreeVarsToBind`.

`Ordering` needs to be wired in for use in the built-in `CmpNat` and
`CmpSymbol` type families, but somehow it was never added to the list
of `wiredInTyCons`, leading to the various oddities observed
in #18185. Easily fixed by moving `orderingTyCon` from
`basicKnownKeyNames` to `wiredInTyCons`.
Fixes #18185.

To determine whether the module is a boot module
