    Extract hard-coded LLVM opt flags into a file
    
    To resolve ticket #11295, I think it makes sense to stop hard-coding
    the pass sequences used by GHC when compiling with LLVM into the
    compiler
    itself.
    
    This patchset introduces a companion to the existing `llvm-targets` file
    called `llvm-passes`. The passes file is a simple association list that
    holds the default LLVM `opt` pass sequence used by GHC. This allows end
    users to easily save their favorite optimization flags when compiling
    with LLVM.
    
    The main benefit for ticket #11295 is that when adding a custom pass
    sequence, it tends to be an extremely long string that would be
    unsightly in the code.
    
    This is essentially part 1 of 2 for ticket #11295.
