libcc1: use std::vector when building function types

Browse Source 
This changes libcc1 to use std::vector in the code that builds
function types.  This avoids some explicit memory management.

libcc1

	* libcp1plugin.cc (plugin_build_function_type): Use std::vector.
	* libcc1plugin.cc (plugin_build_function_type): Use std::vector.
