Stores a v128
vector to the given heap address.
This intrinsic will emit a store with an alignment of 1. While this is provided for completeness it is not strictly necessary, you can also store the pointer directly:
The alignment of the store can be configured by doing a manual store without this intrinsic.
§Unsafety
This intrinsic is unsafe because it takes a raw pointer as an argument, and the pointer must be valid to store 16 bytes to. Note that there is no alignment requirement on this pointer since this intrinsic performs a 1-aligned store.
