`:show paths` dumps the current working directory as well
as the current value of the `importPaths` dynamic flags field.

Make `-ddump-minimal-imports` honour `-dumpdir` flag

The `-dumpdir` flag was added via 668c860b361f16 but failed to
take care of `-ddump-minimal-imports`'s output.
This commit makes up for that omission.

This addresses #7957

Add check for obsolete `darcs.haskell.org` repo urls

to invoke `sync-all` in order to update the local Git repo to point to the new
repository URLs.

Rework how iOS does linking (#8127)

iOS has some particular constraints about how applications can be built:

 * We must generate a static library (.a) since XCode does the final
   link.
 * We need to carefully give the right set of arguments to libtool in
   the case we're generating an archive.
 * Dynamic linking isn't supported.
 * It can only be done on OS X.

This patch cleans up all of the above. We add a new flag `-staticlib`
(only supported on Darwin) that allows us to produce archive files using
libtool, and a -pgmlibtool flag to control which 'libtool' executable to
use.

This fixes #8127. I believe this is the last piece missing from the iOS
cross compiler.

Implement -XNumDecimals (#7266)

Under -XNumDecimals, it's possible to specify an integer literal using
compact "floating point" syntax for any floating literal constant which
also happens to be an integer. This lets us write

    1.2e6 :: Integer

instead of:

    1200000 :: Integer

This also makes some amendments to the users guide.
