Fix Trac #2130: improve derived Ord for primmitive types

This patch does two things:

* (Minor): in TcGenDeriv.careful_compare_Case, test for less-than before
  equality. This should reduce the number of dynamic tests, and also gives
  more scope for optimisation, since less-than tells us more than equality.

* (More important): add special-case derived code for data types that are
  simple wrappers of primitive types. See
Note [Comparision of primitive types]
  This fixes Trac 2130.

All installed Haskell prgms have an inplace and an installed version
- GHC installs a range of compiled Haskell programs in addition to the actual
  compiler.  To ensure that they all run on the platform targeted by the build
  (which may have different libraries installed than the build host), we need
  to make sure that all compiled Haskell code going into an install is build
  with the stage 1 compiler, not the bootstrap compiler.  Getting this right
  is especially important on the Mac to enable builds that work on Mac OS X
  versions that are older than the one performing the build.
- For all installed utils implemented in Haskell (i.e., ghc-pkg, hasktags,
  hsc2hs, runghc, hpc, and pwd) we compile two versions, an inplace version
  and a version for installation.  The former is build by the bootstrap
  compiler during the stage 1 build and the latter is build by the stage 1
  compiler during the stage 2 build.
- This is really very much as the setup for ghc itself, only that we don't use
  separate stage1/ and stage2/ build directories.  Instead, we clean before
  each build.  CAVEAT: This only works properly if invoked from the
  toplevel Makefile.
- Instead of UseStage1=YES (as used by the previous binary-dist-specific
  recompilation), we now use the same $(stage) variables as used for the
  compiler proper - to increase uniformity and to avoid extra conditionals for
  the install target.

Roman Leshchinskiy [Mon, 11 Feb 2008 03:23:50 +0000 (03:23 +0000)]
Symbolic tags for simplifier phases

Every simplifier phase can have an arbitrary number of tags and multiple
phases can share the same tags. The tags can be used as arguments to
-ddump-simpl-phases to specify which phases are to be dumped.
For instance, -ddump-simpl-phases=main will dump the output of phases 2, 1 and
0 of the initial simplifier run (they all share the "main" tag) while
-ddump-simpl-phases=main:0 will dump only the output of phase 0 of that run.

At the moment, the supported tags are:

  main                 The main, staged simplifier run (before strictness)
  post-worker-wrapper  After the w/w split
  post-liberate-case   After LiberateCase
  final                Final clean-up run

The names are somewhat arbitrary and will change in the future.
