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.
