There are a couple of places where regexes are generated interally.
Assert they compile OK.

This is just paranoia. There should be no behavioural changes.

	* src/abg-tools-utils.cc (handle_file_entry): Assert
	internally-generated regex compiles.
	(gen_suppr_spec_from_kernel_abi_whitelists): Assert
	internally-generated regex compiles.
