Subject: [PATCH] Fixes for AutoFDO tests

* Changed several tests to use -fdump-ipa-afdo-optimized instead of -fdump-ipa-afdo
in dg-options so that the expected output can be found

* Increased the number of iterations in several tests so that perf can have
enough sampling events

Contributes to fixing PR gcov-profile/71672.

gcc/testsuite/ChangeLog:

	* g++.dg/tree-prof/indir-call-prof.C: Fix options, increase the number of iterations.
	* g++.dg/tree-prof/morefunc.C: Fix options, increase the number of iterations.
	* g++.dg/tree-prof/reorder.C: Fix options, increase the number of iterations.
	* gcc.dg/tree-prof/indir-call-prof-2.c: Fix options, increase the number of iterations.
	* gcc.dg/tree-prof/indir-call-prof.c: Fix options.
