RFA: don't xfail ptype test

[Michael Elizabeth Chastain]

This patch is returned for more work.

Hmmm.  I agree that this is a bug:

  (gdb) ptype &*"foo"
  type = char [4]

I get that behavior in all of my configurations.

The problem is simply converting XFAIL -> FAIL.  That's correct, but it
doesn't leave a good enough trail for people doing regression analysis.

Could you please file a bug report and then add a comment to the
test script with the bug ID number in it:

  # setup_kfail "gdb/1234"

The bug report can say that this bug is also present in 5.2.

I am willing to file the bug report this evening if you want me to
do that part.
