code review 88190043: liblink, cmd/ld: reenable nosplit checking and test

 // TODO/NICETOHAVE:
 //   - eliminate DW_CLS_ if not used
 //   - package info in compilation units
 //   - assign global variables and types to their packages
 //   - gdb uses c syntax, meaning clumsy quoting is needed for go identifiers. eg
 //     ptype struct '[]uint8' and qualifiers need to be quoted away
