gitlab-template: Emphasize `user facing` label

My sense is that the current mention of the ~"user facing" label is
overlooked by many MR authors.

Let's move this point up in the list to make it more likely that it is
seen. Also rephrase some of the points.

Refactor the simplifier a bit to fix #22761

The core change in this commit, which fixes #22761, is that

* In a Core rule, ru_rhs is always occ-analysed.

This means adding a couple of calls to occurAnalyseExpr when
building a Rule, in
* GHC.Core.Rules.mkRule
* GHC.Core.Opt.Simplify.Iteration.simplRules

But diagosing the bug made me stare carefully at the code of the
Simplifier, and I ended up doing some only-loosely-related refactoring.

* I think that RULES could be lost because not every code path
  did addBndrRules

* The code around lambdas was very convoluted

It's mainly moving deck chairs around, but I like it more now.

compiler: Use NamedFieldPuns for `ModIface_` and `ModIfaceBackend` `NFData`
instances

This is a minor refactor that makes it easy to add and remove fields from
`ModIface_` and `ModIfaceBackend`.

Also change the formatting to make it clear exactly which fields are
fully forced with `rnf`

Refresh profiling docs

I went through the whole of the profiling docs and tried to amend them
to reflect current best practices and tooling. In particular I removed
some old references to tools such as hp2any and replaced them with
references to eventlog2html.

docs: Add section about profiling and foreign calls

Previously there was no documentation for how foreign calls interacted
with the profiler. This can be quite confusing for users so getting it
into the user guide is the first step to a potentially better solution.
See the ticket for more insightful discussion.

Fixes #21764
