SUMMARY
1. Enable supporting the write operation of big archive.
2. the first commit come from https://reviews.llvm.org/D104367
3. refactor the first commit and implement writing symbol table.
4. fixed the bugs and add more test cases in the second commit.

Summary:
when run "llvm-ar cr" on AIX OS , it created a gnu archive, it is not desirable in aix OS.
instead of creating a gnu archive, the patch will print a unsupport message for llvm-ar big archive write operation in AIX OS.
after implement the big archive operation, I will revert the XFAIL: AIX " and "--format=gnu" test cases in the patch.

Print a warning if `llvm-libtool-darwin` if any of the object
files provided by the user have the same file name.
The tool will now print a warning if there is a name collision across:
* Two object files
* An object file and an object file from within a static library
* Two object files from different static libraries
Here is an example of the error:
```
$ llvm-libtool-darwin -static -o archive.a out.o out.o
error: file 'out.o' was specified multiple times.
in: out.o
in: out.o
$ llvm-libtool-darwin -static -o archive.a out.o
$ llvm-libtool-darwin -static -o combined.a archive.a out.o
error: file 'out.o' was specified multiple times.
in: archive.a
in: out.o
```
This change mimics apple's cctools libtool's behavior which always shows a warning in such cases.

Add support for flattening archives while creating static libraries.
Hence, can now pass archives as input in addition to Mach-O binaries.
Furthermore, archives themselves must only conatain Mach-O binaries. As
per cctools' libtool's behavior, llvm-libtool-darwin does not flatten
archives recursively.
