commit 730ac880c5dc23e0f32a2f08d89d4e5d2a583512

    Rip out object splitting
    
    The splitter is an evil Perl script that processes assembler code.
    Its job can be done better by the linker's --gc-sections flag. GHC
    passes this flag to the linker whenever -split-sections is passed on
    the command line.
    
    This is based on @DemiMarie's D2768.
    
    Fixes Trac #11315
    Fixes Trac #9832
    Fixes Trac #8964
    Fixes Trac #8685
    Fixes Trac #8629
