Add an initial implementation of archive symbol table generation. The symbol table has forward references in the file. Instead of allocating a temporary buffer or counting the size and then writing, this implementation writes a dummy value first and patches it once the final value is known. There is room for performance improvement. I will implement them as soon as I get some other features (like a ranlib mode) in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186934 91177308-0d34-0410-b5e6-96231b3b80d8

Add support for the 's' operation to llvm-ar. If no other operation is specified, 's' becomes an operation instead of an modifier. The s operation just creates a symbol table. It is the same as running ranlib. We assume the archive was created by a sane ar (like llvm-ar or gnu ar) and if the symbol table is present, then it is current. We use that to optimize the most common case: a broken build system that thinks it has to run ranlib. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187353 91177308-0d34-0410-b5e6-96231b3b80d8
