 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.
