Vector128/256.Create helpers should be JIT intrinsic and have more optimizations in two steps:

  • import Vector128/256.Create as intrinsics and expand them in codegen
  • cache the results by JIT and just generate "load" for Create call-sites if the arguments of Vector128/256.Create are compile-time constants
