Make Kernel#lambda raise when given non-literal block
Previously, Kernel#lambda returned a non-lambda proc when given a non-literal block and issued a warning under the :deprecated category. With this change, Kernel#lambda will always return a lambda proc, if it returns without raising.
Due to interactions with block passing optimizations, we previously had two separate code paths for detecting whether Kernel#lambda got a literal block. This change allows us to remove one path, the hack done with rb_control_frame_t::block_code introduced in 85a337f for supporting situations where Kernel#lambda returned a non-lambda proc.
