Fix handling of in_flags in update_escape_summary_1

update_escape_summary_1 has thinko where it compues proper min_flags but then
stores original value (ignoring the fact whether there was a dereference
in the escape point).

	PR ipa/103432
	* ipa-modref.c (update_escape_summary_1): Fix handling of min_flags.

(cherry picked from commit a70faf6e4df7481c2c9a08a06657c20beb3043de)
