The promised refresh of the patch set I posted in December.
Changes are:

  * patch 3 is new, improving decode of the xsave insns themselves.
  * patch 16 is new, adding (trivial) support for fsgsbase.
  * I use fewer hflags bits, since we're down to 8 remaining.

Paolo is looking to build on the xsave patches in particular,
and requested that I send the pull request for these.
