This diff adds support for weak definitions, though it doesn't handle weak symbols in dylibs quite correctly -- we need to emit binding opcodes for them in the weak binding section rather than the lazy binding section. What *is* covered in this diff: 1. Reading the weak flag from symbol table / export trie, and writing it to the export trie 2. Refining the symbol table's rules for choosing one symbol definition over another. Wrote a few dozen test cases to make sure we were matching ld64's behavior. We can now link basic C++ programs.
