Simplify `ld.lld --help` message.
Previously, we printed out two lines of help messages for `--foo bar` and `--foo=bar` like this: --soname=<value> Set DT_SONAME --soname <value> Set DT_SONAME --sort-section=<value> Specifies sections sorting rule when linkerscript is used --sort-section <value> Specifies sections sorting rule when linkerscript is used This change eliminates duplicate lines that doesn't contain `=` for such options like this. --soname=<value> Set DT_SONAME --sort-section=<value> Specifies sections sorting rule when linkerscript is used Differential Revision: https://reviews.llvm.org/D47558 llvm-svn: 333596
