+    Fix the --enable-shared build.
+    
+    Currently a build configured with ./configure --enable-shared breaks
+    with an undefined "llvm::cl::parser<llvm::PassInfo
+    const*>::getOption(unsigned int) const" symbol when linking opt.  This
+    body for this symbol gets emitted into Pass.o (along with the destructor
+    for PassNameParser), but gets linked into libLLVM-3.5svn.so with local
+    visibility, causing the link error.
+    
+    This fix uses the existing EXTERN_TEMPLATE machinery to force a globally
+    visible definition for the functions in parser<const PassInfo *> into
+    Pass.o.
