Bit-rotting(?) HUGS-specific code in GHC boot libraries

[Roman Cheplyaka]

Herbert,

Yes, you are right. It was my experience when compiling base with
haskell-names' hs-gen-iface that, unless __GLASGOW_HASKELL__ is defined,
many functions (including H2010) would simply not be defined, and some code
wouldn't even be well-formed Haskell.

First I tried to fix that on the spot, but there were so many cases that I
gave up and made hs-gen-iface define __GLASGOW_HASKELL__ despite not being
one.

I'm not sure these ifdefs nowadays have any value whatsoever.
