      Fix #15012 with a well-placed use of Any · b08a6d75
      Ryan Scott authored
      Previously, derived `Generic1` instances could have associated `Rep1`
      type family instances with unbound variables, such as in the following
      example:
      
      ```lang=haskell
      data T a = MkT (FakeOut a) deriving Generic1
      type FakeOut a = Int
      
      ==>
      
      instance Generic1 T where
        type Rep1 T = ... (Rec0 (FakeOut a))
      ```
      
      Yikes! To avoid this, we simply map the last type variable in a
      derived `Generic1` instance to `Any`.

      Revamp the testsuite framework.  The previous framework was an
      experiment that got a little out of control - a whole new language
      with an interpreter written in Haskell was rather heavyweight and left
      us with a maintenance problem.
      
      So the new test driver is written in Python.  The downside is that you
      need Python to run the testsuite, but we don't think that's too big a
      problem since it only affects developers and Python installs pretty
      easily onto everything these days.
      
      Highlights:
      
        - 790 lines of Python, vs. 5300 lines of Haskell + 720 lines of
          <strange made-up language>.
      
        - the framework supports running tests in various "ways", which should
          catch more bugs.  By default, each test is run in three ways:
          normal, -O, and -O -fasm.  Additionally, if profiling libraries
          have been built, another way (-O -prof -auto-all) is added.  I plan
          to also add a 'GHCi' way.
      
          Running tests multiple ways has already shown up some new bugs!
      
        - documentation is in the README file and is somewhat improved.
      
        - the framework is rather less GHC-specific, and could without much
          difficulty be coaxed into using other compilers.  Most of the
          GHC-specificness is in a separate configuration file (config/ghc).
      
      Things may need a while to settle down.  Expect some unexpected
      failures.

      Add a Makefile here.

      Use makefiles in the subdirectories to ease running the test driver in
      a subdirectory.  It can be run in the following ways:
      
       	make		-- run all the tests in the current directory
       	make verbose	-- as make test, but up the verbosity
       	make accept	-- run the tests, accepting the current output
      
      and you can also set some variables on the command line, eg.
      
      	make accept TESTS=arr001  -- accept an individual test
      	make EXTRA_HC_OPTS='-v'   -- extra flags to the haskell compiler
      	make CONFIG=<config>	  -- use a different test config
      
      this will all go in the docs at some point.
