ubsan: add clang 5.0 support

clang 5.0 changed the layout of the type_mismatch_data structure and
introduced __ubsan_handle_type_mismatch_v1 and
__ubsan_handle_pointer_overflow.

This commit adds support for the new structure layout, adds the
missing handlers and the new types for type_check_kinds.
