<desc>
Load the effective address of a texel from the image specified with the
given index. Returns three staging register: the low/high
32-bits of the address and the internal conversion descriptor. The format
of the internal conversion descriptor is compatible with Bifrost but
omits the register format, as this is specified with the ST_CVT
instruction on Valhall.
Coordinates are specified as 16-bit integers, packed into 32-bit sources.
