   3 ## enabling/disabling individual 8 and 16-bit operations in SIMD blocks
   4
   5 * At the end of a loop, how are the three end operations of 4-wide 8-bit operations to be disabled (to avoid "SIMD considered harmful"?)
   6 * Likewise at the beginning of a loop, how are (up to) the first three operations to be disabled?
   7 * Likewise the last (and first) of 2-wide 16-bit operations?
   8 * What about predication within a 4-wide 8-bit group?
   9 * Likewise what about predication within a 2-wide 16-bit group?
