  -----------
  [X86] Use default attributes for intrinsics

This adds the default attributes (nocallback, nosync, nofree,
willreturn) to some X86 intrinsics. This will be needed to avoid
optimization regressions in the future (once we remove the
readonly -> willreturn implication for intrinsics).

Due to the number of intrinsics, this patch focuses just on the
IntrNoMem intrinsics up to the AVX2 section.
