  [IRBuilder] Handle constexpr-bitcast for IRBuilder::CreateThreadLocalAddress

In case that opaque pointers not enabled, there may be some constexpr
bitcast uses for thread local variables and the design of llvm allow
people to sink constant arbitrarily. This breaks the assumption of
IRBuilder::CreateThreadLocalAddress. This patch tries to handle the
case.
