MPackVector(v1, v2, v3, v4) -> {MIRType_float32x4, MIRType_int32x4}
MLoadVector(elements, offset) -> {MIRType_float32x4, MIRType_int32x4}
MStoreVector(elements, offset, value) where value : {MIRType_float32x4, MIRType_int32x4}
MAddVector(value1, value2) where value1, value2 : {MIRType_float32x4, MIRType_int32x4}
MVectorTypedObject(value) -> MIRType_object (similar to MDerivedTypeObject)

It may be that `MAddVector` is better expressed as a specialization of `MAdd` (this extends to other operators, naturally).

This has been done as part of the SIMD JIT work in bug 1064540 et al.
