George Rimar 9bc20fff4a [ELF] - Fix cref.s test case. 
The intention of -gc-sections flag was to check
that discarded is not in the output. It should be
specified in the executable command line invocation
and also, the symbol must be global as local symbols
are anyways not printed.

George Rimar 5b31b6f12d [ELF] - cref.s: check that we print symbols from archives. NFCI. 
This is consistent with bfd and we already supported it,
though test did not contain the explicit check.

Rui Ueyama db46a62e2b Implement --cref. 
This is an option to print out a table of symbols and filenames.
The output format of this option is the same as GNU, so that it can be
processed by the same scripts as before after migrating from GNU to lld.

This option is mildly useful; we can live without it. But it is pretty
convenient sometimes, and it can be implemented in 50 lines of code, so
I think lld should support this option.
