cmd/5g, cmd/internal/ld, cmd/internal/obj: destutter composite literals

Browse Source 
While here, this changes DWAbbrev's attr field from a [30]DWAttrForm
with zero-termination to a simple []DWAttrForm, and updates its users
accordingly.

Passes "go build -toolexec 'toolstash -cmp' -a std" on linux/amd64.
