commit 07ace5c221adbb1675413a0fac300a9f7913c234

    add -th-file which generates a th.hs file
    
    Summary:
    see Trac #8624
    
    similar functionality is now available
    with -ddump-to-file -ddump-splices
    
    However, users are already accustomed to -ddump-splices
    having a particular format, and this format is not completely valid code
    The goal of -th-file is to dump valid Haskell code
    
    Additionally, the convention of -ddump-to-file is to name the file after
    the flag, so the file is .dump-splices
    Given that the goal of the new flag is to generate valid Haskell,
    The extension should be .hs
    
    Additionally, -ddump-to-file effects all other dump flags
    
    Test Plan:
    look at the output of using the -th-file flag
    and compare it to the output of using -ddump-to-file and -ddump-splices
    I want to add test cases, but just need some pointers on getting started there
