Wrong argument order to Haskell pre-processor (-F, -pgmF, -optF)

So far, and that is what is documented

Additional arguments to the pre-processor can be passed in using the -optF option. These are fed to cmd on the command line after the three standard input and output arguments.

However, GHC 7.7.20131026 passes additional arguments (specified with -optF) before the three standard arguments.

Steps to reproduce:

$ echo '{-# OPTIONS_GHC -F -pgmF ./foo.sh -optF bar #-}' > Foo.hs
$ echo 'echo $*' > foo.sh
$ chmod +x foo.sh
$ ghci Foo.hs

Expected result: Foo.hs Foo.hs /tmp/ghc16665_0/ghc16665_1.hspp bar is printed to stdout

Actual result: bar Foo.hs Foo.hs /tmp/ghc16665_0/ghc16665_1.hspp is printed to stdout

changed milestone to %7.8.1

changed weight to 5

added Tbug Trac import labels

I swapped the arguments to (++) in runPp so that they match the documentation, and added a test to verify the correct operation.
