A `.target` file generated by ghc-toolchain or by configure can become
invalid if the target representation (`Toolchain.Target`) is changed
while the files are not re-generated by calling `./configure` or
`ghc-toolchain` again. There is also the issue of hadrian caching the
dependencies on `.target` files, which makes parsing fail when reading
reading the cached value if the representation has been updated.
This patch provides a better error message in both situations, moving
away from a terrible `Prelude.read: no parse` error that you would get
otherwise.

In Parser.y, the tup_tail rule had the following option

Once this works through PostProcess.hs, it means we add an extra

EpAnn Anchor for the print location for the others.

I believe we don't need to hadle these cases specially at all, which means this MR simply

* Generalise the metric logic by adding an additional field which
allows you to specify how to query for the actual value. Previously
the method of querying the baseline value was abstracted (but always
set to the same thing).
* This requires rejigging how the stat collection works slightly but now
it's more uniform and hopefully simpler.
* Introduce some new "generic" helper functions for writing generic
stats tests.
- collect_size ( deviation, path )
Record the size of the file as a metric
- stat_from_file ( metric, deviation, path )
Read a value from the given path, and store that as a metric
- collect_generic_stat ( metric, deviation, get_stat)
Provide your own `get_stat` function, `lambda way: <Int>`, which
can be used to establish the current value of the metric.
- collect_generic_stats ( metric_info ):
Like collect_generic_stat but provide the whole dictionary of metric
definitions.
{ metric: {
deviation: <Int>
current: lambda way: <Int>
} }
* Introduce two new "size" metrics for keeping track of build products.
- `size_hello_obj` - The size of `hello.o` from compiling hello.hs
- `libdir` - The total size of the `libdir` folder.
* Track the number of modules in the AST tests
- CountDepsAst
- CountDepsParser
This lays the infrastructure for #24191 #22256 #17129

EpaLocation is used to position things. It has two constructors,
EpaSpan holding a SrcSpan, and EpaDelta with a delta position and a
possible list of comments. The comment list is needed because the
location in EpaDelta has no absolute information to decide which
comments should be emitted before them when printing.
But it is also used for specifying the position of a comment. To
prevent the absurdity of a comment position having a list of comments
in it, we make EpaLocation parameterisable, using comments for the
normal case and a constant for within comments.

This patch implements the T2T (term-to-type) transformation in patterns.
Patterns that are checked against a visible forall can now be written
without the `type` keyword:
\(type t) (x :: t) -> ... -- old
\t (x :: t) -> ... -- new
The `t` binder is parsed and renamed as a term pattern (Pat), but
then undergoes a conversion to a type pattern (HsTyPat).
See the new function pat_to_type_pat in compiler/GHC/Tc/Gen/Pat.hs

This MR started as: allow the simplifer to do more in one pass,
arising from places I could see the simplifier taking two iterations
where one would do. But it turned into a larger project, because
these changes unexpectedly made inlining blow up, especially join
points in deeply-nested cases.
The net result is good: a 2% improvement in compile time. The table
below shows changes over 1%.
The main changes are:
* The SimplEnv now has a seInlineDepth field, which says how deep
in unfoldings we are. See Note [Inline depth] in Simplify.Env
* Avoid repeatedly simplifying coercions.
see Note [Avoid re-simplifying coercions] in Simplify.Iteration
As you'll see from the Note, this makes use of the seInlineDepth.
* Allow Simplify.Utils.postInlineUnconditionally to inline variables
that are used exactly once. See Note [Post-inline for single-use things].
* Allow Simplify.Iteration.simplAuxBind to inline used-once things.
This is another part of Note [Post-inline for single-use things], and
is really good for reducing simplifier iterations in situations like
case K e of { K x -> blah }
wher x is used once in blah.
* Make GHC.Core.SimpleOpt.exprIsConApp_maybe do some simple case
elimination. Note [Case elim in exprIsConApp_maybe]
* When making join points, don't do so if the join point is so small
it will immediately be inlined. See Note [Duplicating alternatives]
* Do not add an unfolding to a join point at birth. This is a tricky one
and has a long Note [Do not add unfoldings to join points at birth]
It shows up in two places
- In `mkDupableAlt` do not add an inlining
- (trickier) In `simplLetUnfolding` don't add an unfolding for a
fresh join point
I am not fully satisifed with this, but it works and is well documented.
* Many new or rewritten Notes. E.g. Note [Avoiding simplifying repeatedly]
I discovered that GHC.HsToCore.Pmc.Solver.Types.trvVarInfo was very
delicately balanced. It's a small, heavily used, overloaded function
and it's important that it inlines. By a fluke it was before, but at
various times in my journey it stopped doing so. So I added an INLINE
pragma to it.

This commit adds two things to postInlineUnconditionally:
1. Do not postInlineUnconditionally join point, ever.
Doing so does not reduce allocation, which is the main point,
and with join points that are used a lot it can bloat code.
See point (1) of Note [Duplicating join points] in
GHC.Core.Opt.Simplify.Iteration.
2. Do not postInlineUnconditionally a strict (demanded) binding.
It will not allocate a thunk (it'll turn into a case instead)
so again the main point of inlining it doesn't hold. Better
to check per-call-site.

* No floating at all for join points
* Never inline j x = I x
Example: integerSignum !j = IS (integerSignum# j)
We want this to inline and then cancel with an enclosing case.
But it won't if we have changed it to
integerSignum x = case x of
IN a -> IS (...)
IS b -> IS (...)
IP c -> IS (...)
This involved changing
- UnfoldingGuidance to not say always-inline for j x = Ix
- callSiteInline to inline join points only if there is a real
benefit
