* Add relocations for refernces to non-lazy darwin stubs and implement them correctly. With this change, we can correctly references external globals, and now all but two UnitTests and all but 1 Regression/C tests pass. More importantly, bugpoint-jit will start giving us useful testcases, instead of always telling us that references to external globals don't work :) llvm-svn: 18222
