llvm commit [1] allowed attaching type tag records to modifier BTF records. This is useful for using typedefs that encompass a base type and a type tag, e.g.: typedef struct rbtree __arena rbtree_t; Modify btf_check_type_tags() so that it allows this sequence of records. The function now only checks for record loops in BTF modifier record chains. Rename to btf_check_modifier_chain_length to reflect this. Also expand the BTF modifier traversal code to take into account that type record can be interleaved with other modifier records. In effect this means traversing all modifiers to collect the type tags. Also modify existing selftests to now accept modifier records (const, typedef) that point to type tag records.
