New class allocate_on_obstack
This patch adds a new class allocate_on_obstack, and let dwarf2_per_objfile
inherit it, so that dwarf2_per_objfile is automatically allocated on
obstack, and "delete dwarf2_per_objfile" doesn't de-allocate any space.
gdb:
2018-02-16 Yao Qi <yao.qi@linaro.org>
* block.c (block_namespace_info): Inherit allocate_on_obstack.
(block_initialize_namespace): Use new.
* dwarf2read.c (dwarf2_per_objfile): Inherit allocate_on_obstack.
(dwarf2_free_objfile): Use delete.
* gdbtypes.c (type_pair): Inherit allocate_on_obstack.
(copy_type_recursive): Use new.
* gdb_obstack.h (allocate_on_obstack): New.
