Can you give some more context why this change is needed? What is wrong with the old naming?

Shouldn't 'result' already be a Handle<TypedObject *> instead of a MutableHandle. If I understand this code correctly it doesn't change the result object to another object...

Just personal taste: it seems weird that SimdTypeDescr::TYPE_FLOAT32 (Scalar) actually means SimdTypeDescr::Float32x4. What do you think?

Put aside the GC failures caused by a previous push, it's green, so i'll consider it green (at this point, this might be madness).
