SubjectRe: [PATCH] ubsan: don't mark __ubsan_handle_builtin_unreachable as noreturn

That's actually a bug in GCC. In GCC __ubsan_handle_builtin_unreachable declared
with 'noreturn' and 'const' attributes:


But const attribute doesn't make any sense for function that returns void or doesn't return at all.
Given that gcc-8 has not released yet, it would be better to fix this bug there.
