ghc963 with debugging build flags for MacOS

For @jwiegley to test.

currently based on the keccak pr because i was trying to avoid annoying rebasing. it actually wouldn't have been that bad, but once the keccak native is done i'll rebase.

ghcid hangs when it encounters unparsable CPP

example: ```haskell -- Example.hs {-# LANGUAGE CPP #-} #define = == module Example where main :: IO () main = pure () ``` when loading this module, ghcid freezes up....

ghcid screen flickers/flashes nonstop with -c 'cabal new-repl' when dumping haskell IRs

[WIP] SIMD acceleration

3

Adds SIMD acceleration via [libbase64](https://github.com/aklomp/base64). Depends on the yet-to-be-released haskell bindings library, [libbase64-bindings](https://github.com/chessai/hs-libbase64-bindings). Adds a cabal flag, `simd`, to enable SIMD. Enabled by default. ## Benchmarks I'm running this on...
