@hackage microbase4.15.0.0.0

This package is a hyper-minimal version of base-noprelude. It merely reexports some hardwired modules needed downstream while hiding most things. For example, ghcid will not work without base:System.IO. It also reexports all the "magic" classes that work with stock deriving. Ideally this package wouldn't be needed because ghc-prim would contain everything hardwired, and base would be replaceable.
