[llvm-commits] PATCH: Use modules data layout over subtarget data layout, if it exists.

[Burke, Max]

I was finding that setting the data layout in the IR didn't actually
propagate to the target back ends which was a little confusing :). If
the modules data layout isn't specified then it uses the subtarget data
layout.
