[svn r228] Fixed: when new'ing basic types, the storage was not default initialized. Fixed: the tango/lib/compiler/llvmdc/llvmdc.mak makefile was a bit incorrect. Changed: the basic gc is now the default. Changed: renamed a few temporary names in the LLVM IR output.

char* toStringz (char[] s)

        if (s.ptr)
            if (! (s.length && s[$-1] is 0))
                   s = s ~ '\0';
        return s.ptr;
