C++-ify bp_location
Philippe noticed a memory leak coming from ada_catchpoint_location --
it was not freeing the "function_name" member from its base class:
==14141== 114 bytes in 4 blocks are definitely lost in loss record 1,055 of 3,424

This patch fixes the problem by further C++-ifying bp_location. In
particular, bp_location_ops is now removed, and the "dtor" function
pointer is replaced with an ordinary destructor.
