 FWIW, I just had a peek at the mangler, and it appears that it is now only
 used for TNTC and stack alignment. I also looked for references to the
 mangler with respect to SIMD in the wiki, but couldn't find anything other
 than a blank section
 [https://ghc.haskell.org/trac/ghc/wiki/Commentary/Compiler/Backends/LLVM/Mangler
 here]. I also couldn't find anything WRT Windows and the mangler.

 Finally, according to #4211 (as of commit
 8a1c644af72caf122e73dac801496c055fc82dd9), the mangler is no longer needed
 to fix the stack on OSX. If true, completing this ticket may be the end of
 the mangler.
