-// Some SSE instructions like mov, and, or, xor are available in different
-// variants for different operand types. These variant instructions are
-// equivalent, but on Nehalem and newer cpus there is extra latency
-// transferring data between integer and floating point domains.
-//
-// This pass changes the variant instructions to minimize domain crossings.
