This major version bump was made necessary by
f44333ea which changed the type
signatures of prefetch primops, as well as other changes
such as 051d694f turning `Any` into
an abstract closed type family.

The TH output contains uniques which change too much.
So I took the length of the string instead. Crude,
perhaps too crude, but it'll still show up most significant

These updates these 3 submodules to their respective released tagged
commits. No source-code changes are involved with this update.

The `-unreg` flag was removed in commit dade8ab2 (2007), see #1008.

Summary:
BAD: "." ++ "/" ++ "/absolute/path" == ".//absolute/path"
GOOD: "." </> "/absolute/path" == "/absolute path"

Also replace `++ ".ext"` with `<.> "ext"`. Although it doesn't fix any
bugs in this instance, it might in some other. As a general rule it's
better not to use (++) on FilePaths.

This allow HscTypes to import CoreSyn rather than Rules, which makes
module loops easier to avoid.  At one point in my recent travels this
was important; I'm not sure it's so important now, but it's a good
thing anyway.

In any case CoreRule is defined in CoreSyn, so this move make sense.

The only real change is a new type synonym ImpRuleEdges
No significant changes at all

No change in behaviour

This got broken in commit 5258566e.

Summary:
Commit 71fcc4c0 breaks the 64bit build on Solaris 11. Solaris
is a multi-lib OS so both 32bit and 64bit binaries may  be run, but
by default it compiles to 32bit so that -m64 needs to be added in
the appropriate place when compiling for 64 bits.

Parsing of static and mode flags happens before any session is started,
i.e., before the first call to 'GHC.withGhc'. Therefore, to report
errors for invalid usage of these two types of flags, we can not call
any function that needs DynFlags, as there are no DynFlags available yet
(unsafeGlobalDynFlags is not set either). So we always print "on the
commandline" as the location, which is true except for Api users, which
is probably ok.

When reporting errors for invalid usage of dynamic flags we /can/ make
use of DynFlags, and we do so explicitly in
DynFlags.parseDynamicFlagsFull.

Before, we called unsafeGlobalDynFlags when an invalid (combination of)
flag(s) was given on the commandline, resulting in panics (#9963). This
regression was introduced in 1d6124de.

Also rename showSDocSimple to showSDocUnsafe, to hopefully prevent this
from happening again.

This addresses the Cabal side of #10115 as this pulls in the following two
commits:

> Make sure to pass the package key to ghc
> Haddock: Use --package-{name|version} when available

This pulls in a cherry-picked commit adding support for
the new `--package-name` and `--package-version` flags and thus
helps addressing #10115.

Some ELF link editors default to `--as-needed` and record only
those libraries in DT_NEEDED tags that are needed to resolve
undefined symbols in the shared object to be created.

In Template Haskell we rely on all symbols that were defined
in modules compiled so far to be available in the current
temporary shared object. To prevent the link editor from
dropping the DT_NEEDED tag for the previously linked temporary
shared object we need to override the link editors default and
specify `--no-as-needed` on the command line. This is for GNU ld
and GOLD ld.

This addresses #10110

If one runs the testsuite with a profiling compiler, during the import
of `testlib.py`, `testlib.py` sets the global variable `gs_working`. To
do so, it executes a few statements which require the function
`strip_quotes` to be in scope. But that function only gets defined at
the very end of testlib.py.

This patch moves the definition of `strip_quotes` to testutil.py, which
is imported at the very top of testlib.py. This unbreaks the nightly
builders.

Fixes #8976 and #9873 by making use of the Binutils ld.gold
linker explicit whenever the target is linux/ARM or android/ARM.
This does not affect iOS where Apple provides its own linker.

In order to achieve this, we need to add `-fuse-ld=gold` to
the SettingsCCompilerLinkFlags setting and set
SettingsLdCommand to `ld.gold` (or `${target}-ld.gold` when
cross-compiling). In addition, simplifying the use of
`$(CONF_GCC_LINKER_OPTS_STAGEn)`.

This patch was tested by ensuring that the following worked
as expected:

  * Native builds on linux/x86_64 (nothing changed).
  * Native builds on linux/arm (and uses the gold linker).
  * Linux to linux/arm cross compiles (and uses the cross
    gold linker).
