This is my pauth enhancements from last year, the corresponding gdb
patches for which are nearing merge.  If lore and patchew are to be
believed, I never posted this to the list, only pushed a branch so
that issue #1105 could see it.

Since the cleanups there conflict with the recent m-profile gdbstub
patch set, I set about to resolve those.  In the process, I merged
the secure extension code with the sysregs, since they're simply
presenting different views of the same registers.

Changes for v2:
  * Incorporate feedback for pauth.
  * Rewrite m-profile systemreg and secext xml.
    - Since these are Known to gdb, do not merge the two xml.
    - Upstream gdb only knows about {M,P}SP, but David's extension
      to include the other registers makes sense and Luis confirms
      that it's ok to have extra registers in the two features.
    - Continue to share code between the two xml, but separate
      out the mapping from gdbstub regno to internal enumeration.
