[AutoFDO] Check count initialization to fix ICE with AutoFDO

Fix ICE with AutoFDO by adding initialization check
before accessing IPA counts to avoid issues with uninitialized profile
counts in self-recursive clone processing.

gcc/ChangeLog:

2025-09-08  Kugan Vivekanandarajah  <kvivekananda@nvidia.com>

	* ipa-cp.cc (gather_count_of_non_rec_edges): Check count
	initialization before adding to total.
