[patch/testsuite/cp] exception.exp: partially refurbish

- Subject: [patch/testsuite/cp] exception.exp: partially refurbish
This is a partial redemption of gdb.cp/exception.cc.
This test script is still not ready yet, mostly because I don't know
what the correct behavior of gdb is for "catch catch" and "catch throw".
So it just bails out after "break main; run".
My original goal was to fix the script enough so that it does not
produce ERROR on hp-ux (it's always been disabled for gcc).
I've done that.
Someone else can do more work on it, or I can do more work on it later.
If someone like Daniel J wants to use it to test changes in exception
handling. Just delete the "continue" statement in the middle.
Tested on: native i686-pc-linux-gnu, gcc 2.95.3 3.3.2 HEAD,
-gdwarf-2 and -gstabs+.
I am committing this now.

* gdb.cp/exception.cc: Change <iostream.h> to <iostream>.
* gdb.cp/exception.exp: Use gdb test, gdb_test_multiple.
Use gdb_compile. Remove restriction on gcc. Add some patterns
for recent version of gdb. Delete second half, which was a copy
of the first half with different build flags. This test is
still disabled because it is still not ready for production.

! # This file is part of the gdb testsuite
!
! # Note: These tests are geared to the HP aCC compiler,
! # which has an idiosyncratic way of emitting debug info
! # for exceptions -- it uses a callback mechanism, which
! # is different from the way g++ records exception info
! # for debugging
!
! # The tests are in two parts; the first part deals with
! # statically linked (archive-bound) executables, and the
! # second part repeats those tests with dynamically linked
! # (shared bound) executables. (In the latter case we use
! # a different mechanism to get the address of the notification
! # hook in the C++ support library.) The tests themselves are
! # the same in both parts.

! # IF YOU CHANGE A TEST IN ONE PART MAKE SURE YOU CHANGE IT

! # IN THE OTHER PART TOO!
