I'd say it is the right thing, just should be done at a different spot, instead
of doing it for everything just check it for MEM_REF. I think only MEM_REF can
have ADDR_EXPR of a non-TREE_ADDRESSABLE DECL_P as argument, look e.g. at
mem_ref_refers_to_non_mem_p in expr.c (which checks more than that), or
opf_non_addressable and opf_not_non_addressable handling in
tree-ssa-operands.c.
So, MEM_REF with ADDR_EXPR of a non-TREE_ADDRESSABLE DECL_P IMHO doesn't need
to be instrumented (seems I should modify asan/tsan too).
