Implement -XNumDecimals (#7266)
Under -XNumDecimals, it's possible to specify an integer literal using
compact "floating point" syntax for any floating literal constant which
also happens to be an integer. This lets us write
1.2e6 :: Integer
instead of:
1200000 :: Integer
This also makes some amendments to the users guide.
