Several int128 raw type tests are added to test_btf.
Currently these tests are enabled only for x64 and arm64
for which kernel has CONFIG_ARCH_SUPPORTS_INT128 set.
$ test_btf
......
BTF raw test[106] (128-bit int): OK
BTF raw test[107] (struct, 128-bit int member): OK
BTF raw test[108] (struct, 120-bit int member bitfield): OK
BTF raw test[109] (struct, kind_flag, 128-bit int member): OK
BTF raw test[110] (struct, kind_flag, 120-bit int member bitfield): OK
