there is bug in record_eh_tables that fires in one of C++ testcases where
personality function is present in the same unit and GCC happily optimizes it
out because it fails to set address_taken flag.

Bootstrapped/regtested x86_64-linux, will commit it shortly.

	* cgraphbuild.c (record_eh_tables): Mark personality function as having
	address taken.
