cmd/link: eliminate a couple of unused DWARF attrs The linker's DWARF generation occasionally computes and attaches an attribute X to a type even though the type's abbrev doesn't have the specified attr. For example, the DW_TAG_subroutine_type abbrev entry has no type attribute, but a type attr is given to it (wasting memory). Similarly there are some places where a byte size attr is added to a DIE whose abbrev lacks that attr. This patch trims away a few of these not-needed attrs, saving some very tiny amount of memory.
