Fix #8696 - don't generate static intra-package references.

See the comments in Packages.lhs and the ticket for some more explanation.

This is a temporary fix while we consider a way to re-enable intra-package
references in the mean time.

Fix Haddock formatting
Make Outputable instance for HsDocString useful

Seeing "<document comment>" when trying to debug things in Haddock is
utterly useless and because this instance exists, we can't even make our
own. No instance at all would be better than what it was!

Admittedly, this doesn't produce the nicest output. Perhaps wrapping the
comments in {- -} would be in order but I think it's fine until someone
complains.
Add `withMVarMasked` (re #8818)

Like `withMVar`, but the @IO@ action in the second argument is executed
with asynchronous exceptions masked. This completes the `MVar` API,
which already contained `modifyMVarMasked` and `modifyMVarMasked_`.

Use U+2018 instead of U+201B quote mark in compiler messages

This matches GCC's choice of Unicode quotation marks (i.e. U+2018 and U+2019)
and therefore looks more familiar on the console. This addresses #2507.

Fix #8807.

It turns out that the enhanced repPred function in DsMeta assumed
that the head of any constraint would be a tycon. This assumption
is false. Happily, the solution involved *deleting* code. I
just removed repPred in favor of repTy, and added the HsEqTy case
to repTy, where it should be anyway.
Make distribution tarball compression format configurable

By default, bzip2 compression is selected (which is what has been used
till now). Additionally, by setting the TAR_COMP make variable to one of
the values "bzip2", "gzip", or "xz", an explicit compression format can
be requested for the distribution tarballs. For instance, invoking

  make TAR_COMP=xz sdist-ghc

will result in a tarball `./sdistprep/ghc-7.9.20140226-src.tar.xz`

Fix GMP v4 compatibility.

We had started relying on GMP 5.x (for usage of mpz_powm_sec), but this
is pretty painful on RHEL-esque targets, which still use GMP 4.x.

In the mean time while we're still supporting this, it's easier to just
fallback to mpz_powm when _sec is unavailable, and emit a WARNING for
using the primitive.

This also installs a header, HsIntegerGmp.h, which clients could use for
a fallback.

As a side note, this will probably also help Debian oldstable users who
might have outdated GMP versions (which I believe is the cause for #8666.)

Fix a bug in codegen for non-updatable selector thunks (#8817)

To evaluate most non-updatable thunks, we can jump directly to the
entry code if we know what it is.  But not for a selector thunk: these
might be updated by the garbage collector, so we have to enter the
closure with an indirect jump through its info pointer.
fix comment on allocate() (#8254)
Add hs_thread_done() (#8124)

See documentation for details.
PPC: Fix loads of PIC data with > 16 bit offsets (#7830).

Loads should now handle up to 32 bit offsets.
Add new Data.Bits.Bits(zeroBits) method

This adds a new method to `Bits` which completes the Bits API
with a direct way to introduce a value with all bits cleared.
