[patch/testsuite/cp] classes.cc: extend scope of obj_with_enum

[mec.gnu@mindspring.com (Michael Elizabeth Chastain)]

This patch fixes the problem reported by Corinna V in classes.exp.
I started with Corinna's patch and used Daniel J's suggestion to
hit a different member rather than writing on the same member twice.
This also lets me get rid of a TODO in classes.exp.

Tested on: native i686-pc-linux-gnu, gcc 2.95.3 3.3.3 HEAD, dwarf-2
and stabs+.  With gcc HEAD -gdwarf-2, these results improved:

  -FAIL: gdb.cp/classes.exp: print obj_with_enum (2)
  -FAIL: gdb.cp/classes.exp: print obj_with_enum.priv_enum
  -FAIL: gdb.cp/classes.exp: ptype obj_with_enum.priv_enum
  -FAIL: gdb.cp/classes.exp: ptype obj_with_enum
  +PASS: gdb.cp/classes.exp: print obj_with_enum (2)
  +PASS: gdb.cp/classes.exp: print obj_with_enum.priv_enum
  +PASS: gdb.cp/classes.exp: ptype obj_with_enum.priv_enum
  +KFAIL: gdb.cp/classes.exp: ptype obj_with_enum (PRMS: gdb/57)

I am committing this now.  Thanks Corinna!  And let me know if it
doesn't work for you.

	From Corinna Vinschen with modifications.
	* gdb.cp/classes.cc (enums1): Add a line to extend scope of
	local variable obj_with_enum.
	* gdb.cp/classes.exp (test_enums): Remove TODO note about FAIL
	results with obj_with_enum.
