#2364: Make the maximum tuple size accesible

--------------------------------+-------------------------------------------
In relation with the implementation of a Haskell-embedded DSL, I'm using
Template Haskell to automatically generate instances for tuples.
I'd like to use tuples as big as GHC allows me to. However, the upper size
limit (62 as of GHC 6.8.2) is not accessible by the end user. That forces
me to hardcode the size, which, as you can imagine, is not a good practice
since the value can change in future versions of the compiler.
Thus, I propose to include a constant (e.g. {{{maxTupleSize}}}) somewhere
under GHC.* (maybe GHC.Exts) for that purpose.
