cmd/link: emit DW_AT_data_member_location as a constant
Simplify the DWARF representation of structs by emitting field offsets as constants rather than location descriptions. This was not explicitly mentioned as an option in DWARF2. It is mentioned in DWARF4, but isn't listed in the changes, so it's not clear if this was always intended to work or is an undocumented change. Either way, it should be valid DWARF4.
