  Log Message:
  -----------
  [SveEmitter] Add range checks for immediates and predicate patterns.

Summary:
This patch adds a mechanism to easily add range checks for a builtin's
immediate operands. This patch is tested with the qdech intrinsic, which takes
both an enum for the predicate pattern, as well as an immediate for the
multiplier.
