PR lto/91763
	* lto-streamer-in.c (input_eh_regions): Move EH init to
	lto_materialize_function.
	* tree-streamer-in.c (lto_input_ts_function_decl_tree_pointers):
	Likewise.

lto/
	* lto.c (lto_materialize_function): Initialize EH by looking
	at the function personality and flag_exceptions setting.
