These new versions get rid of AMP warnings
Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org>

After some discussion on ghc-devs@ and elsewhere, it seemed favorable to
make this change as type holes don't let any invalid programs though,
they merely change what the compiler reports in case of certain errors
(namely unbound occurrences, or _ appearing on a LHS.)

Now, the warning mechanism is controlled by -f[no-]warn-type-errors,
just like any other regular warning. Again, on by default.

The documentation and tests have been updated accordingly.

I'm not entirely sure what the intention of this code was, but it was
quite old, and the binary distribution for Windows seems to work OK
nonetheless.

Windows runs the preprocessor using runInteractiveProcess and can't
properly run the generated shell script as a result, since it can't
recognize e.g. a shebang or anything.

Right now the stderr output doesn't match because we don't suppress some
libtool errors, but these seem to be benign. In the mean time, just mark
the text failing (soon to be marked expect_broken)

As Simon pointed out, we should only enable -dynamic-too in the template
haskell case if GHC is dynamic and we're not already compiling in the
dyn way (the dyn way will be switched on by -dynamic-too later in the
pipeline anyway - see pipeLoop)

We're punting on full -dynamic and -dynamic-too support for Windows
right now, since it's still unstable. Also, ensure "Support dynamic-too"
in `ghc --info` is set to "NO" for Cabal.

When compiling a set of modules under --make, we need to check if the
module graph has TemplateHaskell enabled. If it does, then we need to
switch on -dynamic-too for GHCi, so that the linker can properly find
the right dynamic object files.

See merge commit 66693401

This commit also adds a check for a left-over testsuite/.git folder to sync-all

This way, the first time sync-all is called after updating to a
post-testsuite-merge (see #8545) state of ghc.git, the sync-all script
aborts with an error message if a `testsuite/.git` folder is detected and
thus forces the user to take action.

This commit performs a subtree merge of testsuite.git into ghc.git;
The next commit will adapt `sync-all` et al. to the new situation.

At the time of merge, testsuite.git was at commit
[998a816ae89c4fd573f4abd7c6abb346cf7ee9af/testsuite]

The following steps have been used to accomplish this merge:

1. Clone a fresh testsuite.git copy (& cd into)

2. Remove accidentally committed binary files from history

 git filter-branch \
  --index-filter "git rm -r --cached --ignore-unmatch \
    tests/haddock/should_compile_flag_nohaddock/a.out \
    tests/haddock/should_compile_noflag_nohaddock/a.out \
    tests/ghc-regress/haddock/should_compile_flag_nohaddock/a.out \
    tests/ghc-regress/haddock/should_compile_noflag_nohaddock/a.out \
    tests/ghc-regress/dph/diophantine/dph-diophantine-fast \
    tests/ghc-regress/dph/diophantine/dph-diophantine-opt \
    tests/ghc-regress/dph/primespj/dph-primespj-fast \
    tests/ghc-regress/dph/quickhull/dph-quickhull-fast \
    tests/ghc-regress/dph/smvm/dph-smvm \
    tests/ghc-regress/dph/sumnats/dph-sumnats \
    tests/ghc-regress/dph/words/dph-words-fast \
    tests/ghc-regress/plugins/plugins01" \
   HEAD

3. Rename all paths in testsuite.git to be prefixed with `testsuite/`

 git filter-branch -f --prune-empty --tree-filter \
  "mkdir -p testsuite; \
   git ls-tree --name-only \$GIT_COMMIT | xargs -I files mv files testsuite/"

4. cd into ghc/ checkout, and perform subtree merge of testsuite into ghc
   (see also http://nuclearsquid.com/writings/subtree-merging-and-you/)

 cd ../ghc/
 git remote add -f testsuite ../testsuite/.git
 git merge -s ours --no-commit testsuite/master
 git read-tree --prefix=/ -u testsuite/master

Richard, you may want to regenerate the PDF
as I get

! LaTeX Error: File `stmaryrd.sty' not found.

with my setup and do not want to mess things up.

Also for me ?? appear twice on top of the page 13
and I have tp 'rm core-spec.pdf; make' to get it
right.
