Thanks for the pull request.

Please update the pull request to remove the default arguments to the declarations and calls to the following routines.

void target_enter_data(int64_t device_id, ompt_scope_endpoint_t scope = ompt_scope_begin);
void target_exit_data(int64_t device_id, ompt_scope_endpoint_t scope = ompt_scope_begin);
void target_update(int64_t device_id, ompt_scope_endpoint_t scope = ompt_scope_begin);
void target(int64_t device_id, ompt_scope_endpoint_t scope = ompt_scope_begin);

Hi, John,

I have removed those default arguments. In addition, I add a new ompt routine for data mappings in declare target construct. If there is any other problem in the pull request, please let me know. I may submit more commits if I find other missing ompt routines.

Best,
Lechen
