+// Immeidates Pooling and Randomization options

"Immediates" misspelled.

I would prefer not so much capitalization, such as "Options for pooling and
randomization of immediates".

Done.

+  NoneImmediatesRandomizationPooling,

For non-scoped enum values in the top-level (Ice) namespace, let's use a common
prefix on the values.  E.g.,
  RPI_None,
  RPI_Randomize,
  RPI_Pool

Done.
