Fix indir-call-prof-2.c with AutoFDO

Browse Source 
indir-call-prof-2.c has -fno-early-inlining but AutoFDO can't work without
early inlining (it needs to match the inlining of the profiled binary).
I changed profopt.exp to always pass -fearly-inlining for AutoFDO.
With that change the indirect call inlining in indir-call-prof-2.c happens in the early inliner
so I changed the dg-final-use-autofdo.

Contributes to fixing PR gcov-profile/71672

gcc/testsuite/ChangeLog:

	* gcc.dg/tree-prof/indir-call-prof-2.c: Fix dg-final-use-autofdo.
	* lib/profopt.exp: Pass -fearly-inlining when compiling with AutoFDO.
