linux-user: Emulate the Anonymous: keyword in /proc/self/smaps
Core dumps produced by gdb's gcore when connected to qemu's gdbstub lack stack. The reason is that gdb includes only anonymous memory in core dumps, which is distinguished by a non-0 Anonymous: value. Consider the mappings with PAGE_ANON fully anonymous, and the mappings without it fully non-anonymous.
