This adds ToXML methods to encode RegisterFlags and its fields into XML according to GDB's target XML format: https://sourceware.org/gdb/onlinedocs/gdb/Target-Description-Format.html#Target-Description-Format lldb-server does not use libXML to build XML, so this follows the existing code that uses strings. Indentation is used so the result is still human readable. ``` <flags id=\"Foo\" size=\"4\"> <field name=\"abc\" start=\"0\" end=\"0\"/> </flags> ``` This is used by lldb-server when building target XML, though no one sets any fields yet. That'll come in a later commit.
