This patch tweaks `exprIsConApp_maybe`, `exprIsHNF` and friends, and Demand
Analysis so that they exploit and maintain strictness of DataCon workers. See
`Note [Strict fields in Core]` for details.
Very little needed to change, and it puts field seq insertion done by Tag
Inference into a new perspective: That of *implementing* strict field semantics.
Before Tag Inference, DataCon workers are strict. Afterwards they are
effectively lazy and field seqs happen around use sites. History has shown
that there is no other way to guarantee taggedness and thus the STG Strict Field
Invariant.
Knock-on changes:
* I reworked the whole narrative around "Tag inference".
It's now called "EPT enforcement" and I recycyled the different overview
Notes into `Note [EPT enforcement]`.
* `exprIsHNF` previously used `exprOkForSpeculation` on unlifted arguments
instead of recursing into `exprIsHNF`. That regressed the termination
analysis in CPR analysis (which simply calls out to `exprIsHNF`), so I made
it call `exprOkForSpeculation`, too.
* There's a small regression in Demand Analysis, visible in the changed test
output of T16859: Previously, a field seq on a variable would give that
variable a "used exactly once" demand, now it's "used at least once",
because `dmdTransformDataConSig` accounts for future uses of the field
that actually all go through the case binder (and hence won't re-enter the
potential thunk). The difference should hardly be observable.
* The Simplifier's fast path for data constructors only applies to lazy
data constructors now. I observed regressions involving Data.Binary.Put's
`Pair` data type.
* Unfortunately, T21392 does no longer reproduce after this patch, so I marked
it as "not broken" in order to track whether we regress again in the future.
Fixes #20749, the satisfying conclusion of an annoying saga (cf. the ideas
in #21497 and #22475).
Compiler perf generally improves, sometimes drastically:

I looked at T17516. It seems we do a few more simplifier iterations and end up
with a larger program. It seems that some things inline more, while other things
inline less. I don't see low-hanging fruit.
I also looked at MultiLayerModulesTH_OneShot. It appears we generate a strange
join point in the `getUnique` method of `Uniquable GHC.Unit.Types.Module` that
should better call-site inline, but does not. Perhaps with !11492.
NoFib does not seem affected much either:

I had a look at last-piece. Nothing changes in stg-final, but there is a bit
of ... movement around Data.Map.insert's use of GHC.Exts.lazy that is gone in
stg-final.

This is a pure refactor, tidying up some inconsistent naming:

isEqPrimPred --> isEqPred
isReprEqPrimPred --> isReprEqPred
mkPrimEqPred --> mkNomEqPred
mkReprPrimEqPred --> mkReprEqPred
mkPrimEqPredRold --> mkEqPredRole
Plus I moved mkNomEqPred, mkReprEqPred, mkEqPredRolek
from GHC.Core.Coercion to GHC.Core.Predicate
where they belong. That means that Coercion imports Predicate
rather than vice versa -- better.

It turned out (#25387) that the fix to #15725 was not quite right:
commit 48efbc04bd45d806c52376641e1a7ed7278d1ec7
Date: Mon Oct 15 10:25:02 2018 +0200
Fix #15725 with an extra Sym
Optimising InstCo is quite subtle, and the invariants surrounding
the LiftingContext in the coercion optimiser were not stated explicitly.
This patch refactors the InstCo optimisation, and documents these
invariants. See
* Note [Optimising InstCo]
* Note [The LiftingContext in optCoercion]
I also did some refactoring of course:
* Instead of a Bool swap-flag, I am not using GHC.Types.Basic.SwapFlag
* I added some invariant-checking the coercion-construction functions
in GHC.Core.Coercion.Opt. (Sadly these invariants don't hold during
typechecking, becuase the types are un-zonked, so I can't put these
checks in GHC.Core.Coercion.)

I don't have a small repro case (it came up when building horde-ad,
which uses typechecker plugins). It should be possible to make a
repro case, by using a plugin (which builds a UnivCo) but I decided
it was not worth the bother. The bug is egregious and easily fixed.

This patch fixes foreign stub handling logic in `hscParsedDecls`.
Previously foreign stubs were simply ignored here, so any feature that
involve foreign stubs would not work in ghci (e.g. CApiFFI). The patch
reuses `generateByteCode` logic and eliminates a large chunk of
duplicate logic that implements Core to bytecode generation pipeline
here. Fixes #25414.

This patch removes unused `USE_REPORT_PRELUDE` code paths from the
tree. They have been present since the first git revision
4fb94ae5e5d632748fa2e6c35e259eccc5a1a3f4, and might have been useful
for debugging purposes many years ago, but these code paths are never
actually built. Removing these ease maintenance of relevant modules in
the future, and also allows us to get rid of `CPP` extension in those
modules as a nice byproduct.
