Fixes some core-lint errors when compiling with profiling

Now included:
    - all language flags
    - all filename-related flags (-i, -osuf, -hidir etc.)
    - all CPP-related flags (-I, -D, -U)

* if -XParallelArrays is given, the symbols for the desugarer are
  taken from 'Data.Array.Parallel' (from whichever package is
  exposed and has the module — the home package is fine, too)
* if -fvectorise is given, the symbols for the vectoriser are
  taken from 'Data.Array.Parallel.Prim' (as above)

(There is one wired in symbol left, namely the data constructor
'base:GHC.PArr.[::]. It'll die another day.)

As usual it was to do with the handling of bottoms,
but this time it wasn't terribly subtle; I was using
andArityType (which is designed for case branches) as
a cheap short cut for the arity trimming needed with
a cast.  That did the Wrong Thing for bottoming
expressions.  Sigh.

(fix build failure with -split-objs)

Also, use the Win32 API (CreateThread) instead of the CRT API
(_beginthreadex) for thread creation.

This means ghci now correctly picks up the package flags
for tab completion.

iWe were adding c:/... to $PATH, but : is the separator
in $PATH.

Ensures that these handles are flushed even when the RTS is being used
as a library, with no main.

Needs a corresponding change to libraries/base.

The special dead-code eliminator in CorePrep was not taking into
account free variables inside Breakpoint ticks.

Make it a separate section to help it stand out, and add an
example containing multiple defaults for a single type.

So the .prof file will be UTF-8.  This is mostly ok, except that the
RTS doesn't calculate the column widths correctly (it assumes bytes =
chars).

hp2ps doesn't do anything sensible with Unicode strings, it just dumps
the bytes into the .ps file.

Fix validate by moving OPTIONS -fno-warn-tabs Validate fixed for Mac OS X 10.5 and Linux. For both: compiler/nativeGen/PPC/Instr.hs compiler/nativeGen/SPARC/Instr.hs failed to (stage1) build. For Mac OS X, but mysteriously not for Linux: compiler/basicTypes/Id.lhs compiler/basicTypes/Name.lhs failed during haddock'ing.
