This patch was originally developed by Max Bolingbroke, and worked on
further by Austin Seipp.  It allows you to write a Core-to-Core pass
and have it dynamically linked into an otherwise-unmodified GHC, and
run at a place you specify in the Core optimisation pipeline.

Main components:
  - CoreMonad: new types Plugin, PluginPass
               plus a new constructor CoreDoPluginPass in CoreToDo

  - SimplCore: stuff to dynamically load any plugins, splice
    them into the core-to-core pipeline, and invoke them

  - Move "getCoreToDo :: DynFlags -> [CoreToDo]"
      which constructs the main core-to-core pipeline
      from CoreMonad to SimplCore
    SimplCore is the driver for the optimisation pipeline, and it
    makes more sense to have the pipeline construction in the driver
    not in the infrastructure module.

  - New module DynamicLoading: invoked by SimplCore to load any plugins
    Some consequential changes in Linker.

  - New module GhcPlugins: this should be imported by plugin modules; it
    it not used by GHC itself.

See the long Note [Binders in Template Haskell] in Convert.lhs
which explains it all.  This patch fixes Trac #5037.

The key change is that NameU binders (ones made up by newName in
Template Haskell, and by TH quotations) now make Exact RdrNames again,
rather than making RdrNames with heavily encoded OccNames like x[03cv].
(This encoding is what was making #5037 fail.)

This fixes the ghcpkg05 test failure.
(ghc-pkg check was complaining because the mtl docs didn't exist).

Unfortunately, I couldn't remove all incidences of runCmmContFlowOpt
from HscMain; in particular, there is a Cmm conversion testing
facility which may run with only control flow optimizations, which
I preserved the semantics of.  Given the state of the current
codegen, this code might be moribund anyway.

  Module imports form a cycle:
    module `Foo4' imports `Foo'
            which imports `Foo2'
            which imports `Foo3'
            which imports `Foo4'

It doesn't make sense to specialise class methods -- their
code is simply a record selector.  Moreover, such methods
don't (currently) have an inl_sat field in their InlinePragma
which made DsBinds.makeCoreArity bleat.

This patch just ignores such pragmas, with a warning.

The following patches were ported:
