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.
