  Add type families: Tuple, Constraints, Tuple#, Sum# (#27179)
  
  These type families map tuples of types to the corresponding Tuple<N>,
  Tuple<N>#, CTuple<N>, and Sum<N># types. Some examples at N=2:
  
  	Tuple (Int, Bool)          = Tuple2 Int Bool
  	Constraints (Show a, Eq a) = CTuple2 (Show a) (Eq a)
  	Tuple# (Int#, Float#)      = Tuple2# Int# Float#
  	Sum# (Int#, Float#)        = Sum2# Int# Float#
  
  See GHC Proposal #145 "Non-punning list and tuple syntax".
  
  To make the Sum# instance at N=64 possible, this patch also introduces
  the Sum64# constructor declaration and bumps mAX_SUM_SIZE from 63 to 64.
  
  Metric Increase:

  rts: Add IPE event class for -l
  
  This commit adds a new IPE event class to the -l RTS flag.
  Previously, IPE events were enabled unconditionally.
  However, the IPE events can easily grow to hundreds or thousands of megabytes.
  With the new event class you can pass, e.g., -l-I to disable IPE events.
