I'd really like to see a clearer explanation about what this fixes.
Something like

"These intrinsics will be used to implement X, Y, Z from $extension,
 which support additional types (including 64-bit types). For 64-bit
 types get_nir_dest() returns ..., so we need to force the type to D
 since it always returns a bool."
