Fixes trac #2956

 * Fix loading of 64bit floats
 * Put SRT and other read only static data in the .text segment

  * Use BlockIds in branch instructions instead of Imms.
  * Assign FP values returned from C calls to the right regs
  * Fix loading of F32s
  * Add a SPARC version of the FreeRegs map to the linear allcator.

This makes about half the tests in codeGen/should_run work.

In RTS tracing code, need to untag the pointer before trying 
to load the info table in printClosure()

Linux defines PTHREAD_MUTEX_ERRORCHECK = PTHREAD_MUTEX_ERRORCHECK_NP
anyway, so there's no need to special-case it.

Otherwise ASSERT_LOCK_HELD will cause deadlocks

    Don't check pthread_mutex_*lock() only on Linux and/or only if DEBUG
    is defined. The return values of those functions are well defined
    and should be supported on all operation systems with pthreads. The
    checks are cheap enough to do them even in the default build (without
    -DDEBUG).
    
    While here, recycle an unused macro ASSERT_LOCK_NOTHELD, and let
    the debugBelch part enabled with -DLOCK_DEBUG work independently
    of -DDEBUG.

This patch caused problems on Mac OS X, undoing until we can do it better.

rolling back:

  * Always check the result of pthread_mutex_lock() and pthread_mutex_unlock().

In particular, config.guess should now know about x86_64-pc-solaris2

> import System.Process
Could not find module `System.Process':
  There are files missing in the process-1.0.1.1 package,
  try running 'ghc-pkg check'.
  Use -v to see a list of the files searched for.

We now look for missing files (including .hi files), and report all
the packages that are transitively broken.

$ ghc-pkg check 
There are problems in package syb-0.1.0.0:
  dependency foo-4.0.0.0 doesn't exist
There are problems in package process-1.0.1.1:
  file System/Process.hi is missing

The following packages are broken, either because they have a problem
listed above, or because they depend on a broken package.
syb-0.1.0.0
process-1.0.1.1
base-3.0.3.0
Cabal-1.7.0
haskell98-1.0.1.0
haddock-2.4.2
ghc-6.11

- Factor out code for applying newtypes from Check into CoreUtils
- Use this code in Prep, which allowed for some simplification
- Change Merge and ElimDeadCode to not flatten top-level binds
- Add a flag for elimDeadCode to tell it whether to keep
exported bindings or not.
- Other things.

Print out the same recursive/non-recursive binding groups
that existed in internal Core in an External Core file,
rather than dumping everything into one big recursive group.
