Jan Kratochvil - April 6, 2015, 5:26 p.m.
Provide a way to access current 'scope' during struct the do_module_cleanup
stage and associate more data with it.

It should be all sub-classed but AFAIK GDB does not require C++ compiler yet.

gdb/ChangeLog
2015-04-06  Jan Kratochvil  <jan.kratochvil@redhat.com>

	* cli/cli-script.c (execute_control_command): Update
	eval_compile_command caller.
	* compile/compile-object-load.c (compile_object_load): Add parameters
	scope and scope_data.  Set them.
	* compile/compile-object-load.h (struct compile_module): Add fields
	scope and scope_data.
	(compile_object_load): Add parameters scope and scope_data.
	* compile/compile-object-run.c (struct do_module_cleanup): Add fields
	scope and scope_data.
	(compile_object_run): Propage the fields scope and scope_data.
	* compile/compile.c (compile_file_command, compile_code_command):
	Update eval_compile_command callers.
	(eval_compile_command): Add parameter scope_data.  Pass it plus scope.
	* compile/compile.h (eval_compile_command): Add parameter scope_data.
	* defs.h (struct command_line): Add field scope_data.
