[PATCH] gdb.c++/method.exp: xfail for missing const

[Michael Elizabeth Chastain]

How about this for printing "this" in a const method?

It reports PASS if the required "const" is present.
It reports (XFAIL|FAIL) with "missing const" if required "const" is missing.
  XFAIL if stabs debugging format
  FAIL  if any other debugging format
It reports FAIL for any other output.

# Check access to this pointer
#
# gcc versions up to 3.0.4 with -gstabs+ do not emit "const" indicators,
# so the output is "A *".  It should be "const A *" or "const A * const".
