            Bug ID: 26198
           Summary: Reconsider merging strings is strtab
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs

In r257017 we stopped merging string in strtab. When linking lld with
Release+Asserts that caused an 11% speedup and a 3% strtab size increase.

We should experiment with still using StringTableBuilder but not calling
finalize. This will avoid the tail merging and string copying, but would still
avoid having two identical strings in the table.
