In this linker model, adding an undefined symbol may trigger chain reactions. It may trigger a Lazy symbol to read a new file. A new file may contain a directive section, which may contain various command line options. Previously, we didn't handle chain reactions well. We visited /include'd symbols only once, so newly-added /include symbols were ignored. This patch fixes that bug. Now, the symbol table is versioned; every time the symbol table is updated, the version number is incremented. We repeat adding undefined symbols until the version number does not change. It is guaranteed to converge -- the number of undefined symbol in the system is finite, and adding the same undefined symbol more than once is basically no-op. llvm-svn: 240177
