Return trivial default constructor to half type. Without default constructor it is impossible to create union with half type. Changed implementation of marray and half_vec constructors for optimizing them to use half with trivial default constructor. Update files accordingly to returned half trivial default constructor. This patch corrects #4518 Signed-off-by: mdimakov maxim.dimakov@intel.com

Add default constexpr constructor for half and host half classes, and also for half_vec struct.
Due to bitselect built-in uses union with half specialization, but object of a class without trivial constructor cannot be a member of union, the builtins_helper struct was added. This struct allow to use host half class instead of main half class in the builtin.
