- No need to add other-modules by hand
- Works on OSX (.sh didn't)
- Found missed files!

The d36a2d7c commit was overzealous,
as it not only removed the obsolete GHC HEAD entry, but also the
non-GHC HEAD entry which was there on purpose.

Per the comment at [1] it is no longer necessary.

Just added the build to the list of allowed failures before,
not to the actual list of things to build :-)

This reverts commit 6913400f.

Just as we don't store the package index in the cache. That said, in
future once we're using the secure repo routinely it'd be ok to
occasionally cache the index if we wanted, to save downloads. But since
it does change frequently, we wouldn't want to update the cache
frequently.

GHC 7.4 is more than four years old now, well outside our three-year
support window. (Actually, GHC 7.6 is outside our support window too,
but I don't have any pending patches which are broken with that
version.)

1. Unbreak the deployment script (hopefully the last time).
2. No longer attempt to upload docs when building from non-main repos.

Fixes #3592.

Lots of changes:

    - When possible, we use the container infrastructure (sudo: false)
      rather than Google Compute Engine infrastructure (sudo: required).
      Unfortunately, we can't use GCE for the Linux builds, where
      reduced RAM available hoses are GHC build.

    - Switched from using ./Setup and old-style cabal to new-build.
      There are numerous great benefits but the best is that
      .cabal/store can be cached on Travis, leading to huge speedups
      on the build.  Downside is we need to string-and-ceiling-wax
      support for test/haddock/etc.

    - I stopped bootstrapping on every build we do; instead there
      is a separate bootstrap build we do to make sure that that
      is working.  This also speeds up the basic builds since
      we are not building Cabal/cabal-install multiple times.

    - There are some hacks.  The big one is setting CABAL_BUILDDIR
      explicitly; this smooths over quite a few infelicities in
      the current new-build implementation.

[ci skip]

Fixes #3543.

Now that we bootstrap Cabal and cabal-install, we don't have to install
the package anymore.

It makes the build fail due to timeout.
