A lot of those can be removed if Random has instances for Word* by default. Is there any reason they aren't already instances?

I see several instances for base types - the random package ought to provide these.

Proposal:

Add Random instances for:

* all the types in Data.Int: (Int is already provided) Int8, Int16, Int32, Int64

* all the types in Data.Word: Word, Word8, Word16, Word32, Word64

* almost all the types in Foreign.C.Types: CChar, CSChar, CUChar, CShort, CUShort, CInt, CUInt, CLong, CULong, CPtrdiff, CSize, CWchar, CSigAtomic, CLLong, CULLong, CIntPtr, CUIntPtr, CIntMax, CUIntMax,

CFloat, CDouble

Does it make sense to have Random instances for CClock and CTime?
