<pre>In r287699, I changed lld to not emit an error when a bitcode file passed as
input doesn't contain a datalayout.
I previously added this check because we didn't set a default datalayout in lld
and that caused the linker to crash.
Now, lld switched to `lib/LTO` and we always call setDataLayout on the
LTOModule.
Mehdi (and Chandler) pointed out it would be a good thing(TM) to warn (or
error?) on modules without a datalayout. I agree, and I think the right place
to implement this (at least initially is lib/LTO).</pre>
