rts: Add stg_copyArray_barrier to RtsSymbols list

It's incredible that this wasn't noticed until now.

testsuite: Output performance test results in tabular format
this was suggested in #18417.

Change the print format of the values.
* Shorten commit hash
* Reduce precision of the "Value" field
* Shorten metrics name
  * e.g. runtime/bytes allocated -> run/alloc
* Shorten "MetricsChange"
  * e.g. unchanged -> unch, increased -> incr

And, print the baseline environment if there are baselines that were
measured in a different environment than the current environment.

If all "Baseline commit" are the same, print it once.

Make the forall-or-nothing rule only apply to invisible foralls (#18660)

This fixes #18660 by changing `isLHsForAllTy` to
`isLHsInvisForAllTy`, which is sufficient to make the
`forall`-or-nothing rule only apply to invisible `forall`s. I also
updated some related documentation and Notes while I was in the
neighborhood.

gitlab-ci: Handle distributions without locales

Previously we would assume that the `locale` utility exists. However,
this is not so on Alpine as musl's locale support is essentially
non-existent.

(cherry picked from commit 17cdb7ac3b557a245fee1686e066f9f770ddc21e)

gitlab-ci: Accept Centos 7 C.utf8 locale

Centos apparently has C.utf8 rather than C.UTF-8.

Use "to" instead of "2" in internal names of conversion ops

Change the constructors for the primop union, and also names of the
literal conversion functions.

"2" runs into trouble when we need to do conversions from fixed-width
types, and end up with thing like "Int642Word".

Only the names internal to GHC are changed, as I don't want to worry
about breaking changes ATM.

Postpone associated tyfam default checks until after typechecking

Previously, associated type family defaults were validity-checked
during typechecking. Unfortunately, the error messages that these
checks produce run the risk of printing knot-tied type constructors,
which will cause GHC to diverge. In order to preserve the current
error message's descriptiveness, this patch postpones these validity
checks until after typechecking, which are now located in the new
function `GHC.Tc.Validity.checkValidAssocTyFamDeflt`.

Fixes #18648.

DynFlags: add OptCoercionOpts

GHC.Core.Coercion.Opt

DynFlags: add UnfoldingOpts and SimpleOpts

Milestone: after this patch, we only use 'unsafeGlobalDynFlags' for the
state hack and for debug in Outputable.

DynFlags: add sm_pre_inline field into SimplMode (#17957)

Remove GENERATED pragma, as it is not being used

@alanz pointed out on ghc-devs that the payload of this pragma does
not appear to be used anywhere.

I (@bgamari) did some digging and traced the pragma's addition back to
d386e0d2 (way back in 2006!).

It appears that it was intended to be used by code generators for use
in informing the code coveraging checker about generated code
provenance. When it was added it used the pragma's "payload" fields as
source location information to build an "ExternalBox". However, it
looks like this was dropped a year later in 55a5d8d9.  At this point
it seems like the pragma serves no useful purpose.

Given that it also is not documented, I think we should remove it.

Updates haddock submodule

Closes #18639

hadrian: Don't include -fdiagnostics-color in argument hash

Otherwise the input hash will vary with whether colors are requested,
which changed with `isatty`.

Fixes #17983.
