exec_set_find_memory_regions is used to modify the exec target.
However, it only has a single caller, and so it is much clearer to
simply set the appropriate field directly. It's also better for the
coming multi-target world to avoid this kind of global state change
anyway.

* gcore.h (objfile_find_memory_regions): Declare.
* gcore.c (objfile_find_memory_regions): No longer static. Add
"self" argument.
(_initialize_gcore): Don't call exec_set_find_memory_regions.
* exec.c: Include gcore.h.
(exec_set_find_memory_regions): Remove.
(exec_find_memory_regions): Remove.
(exec_do_find_memory_regions): Remove.
(init_exec_ops): Update.
* defs.h (exec_set_find_memory_regions): Remove.
