```
wasm: Implement elem_ptr

This implements lowering elem_ptr for decl's and constants.
To generate the correct pointer, we perform a relocation by using the addend
that represents the offset. The offset is calculated by taking the element's size
and multiplying that by the index.

For constants this generates a single immediate instruction, and for decl's
this generates a single pointer address.

```
