The hsc2hs-0.68.4 release was already revised with a lower bound `base >= 4.12` to
mitigate the issue solver-side
(http://hackage.haskell.org/package/hsc2hs-0.68.4/revisions/)

This improves upon #9

This commit was performed automatically by a script.

All lower bounds except those for `process` (due to showCommandForUser)
match the versions of boot libraries shipped w/ GHC 7.0

See https://ghc.haskell.org/trac/ghc/ticket/13896

While I was in town, I also:

* Added a cabal.project file
* Updated .gitignore to include cabal new-build artifacts

and update GHC 8.2.1 to GHC 8.2.2 while at it

The previous script didn't run the testsuites yet

As this would require us to declare `cabal-version: 2.0` in the
cabal package description.

This regression was introduced in 9c13b192

Fixes #6

Adds a crude at&t assembly parser to resolve constants

update travis.yml to not try to build the testsuite on 7.0 and 7.2
which won't work, because the dependencies 'call-stack' depends
on base >= 4.5, which is a dependency of hspec-core.

Also updates the assembly files, to drop the `\n` test, which might
end up as `\12`, as `\12`, `\x0a` and `\n`, testing this properly
would require some form of normalization, which we don't have yet.

Our current approach is taken from autoconf, and requires a binary search to
find constants.  This is not only very time consuming but also breaks when the
compiler fails to recognize an expression as constant.  As such we ask the
compiler to produce assembly, crudely parse that assembly and try to extract the
constant directly from the generated assembly.

Summary:
This removes the make concurrency bug from the CrossCompilation
fix, and uses the same appraoch `utils/unlit` already uses. See:

In 598303cb the Paths_hsc2hs module was added to the other-modules.
As such, it should be dropped from the ghc.mk

If the `IN_GHC_TREE` CPP macro is defined (controlled by the `in-ghc-tree` cabal flag),
as a last resort, we also try to locate the template relative to the location of the currently
executed `hsc2hs`. Note that this is a hack to work around
only partial relocatable support in cabal, and is here to allow the `hsc2hs`
built and shipped with ghc to be relocatable with the ghc
binary distribution it ships with.

Note that on Windows, `getExecutablePath` doesn't yet operate correctly
in the presence of symlinks; but this should note have any detrimental
effects. This will be fixed/improved in future `base` version.

This is basically the `hsc2hs` section from the GHC user's guide

This was detected by `-Wmissing-home-modules`

Note: GHC 7.0.4 cannot use installed `process`

This should fix Trac #14297.  When building a cross compiler, we have rather little use
of utilities that do not run on the host, where the compiler runs. As such we should
build the utilities with the bootstrap (stage 0) compiler rather than witht he
in-tree (stage 1) compiler when CrossCompiling.

This used to results in the utilities we ship in the binary distribution to be built for
the wrong host.  This diff tries to rectify the situation and allow the binary distribution
to contain the utilities for the host when CrossCompiling.

Summary:
With the old definition clang gives this error:
```
error: '(anonymous struct at example.cpp:15:3)'
  cannot be defined in a type specifier
```
This makes it work under clang.

Test Plan:
Test with https://godbolt.org/g/kIBwyP and look at the
assembly.

Summary:
Keep track of column numbers and inform GHC whenever the column number
could be potentially desynchronized from the original source code.  This
should fix GHC #13388 on Trac.

Test Plan: validate
