Added test case for bug #100
Removed dubious check for not emitting static private global in other modules without access. This should be handled properly somewhere else, it's causing unresolved global errors for stuff that should work (in MiniD)

Fixed the optimizer thing, since llvm PR 2800 is already fixed, users need to upgrade LLVM to latest svn.
