<pre>This causes issues when doing thinlto builds, where one module is built with
-fno-xray-instrument while another is built with -fxray-instrument, then at
link-time the re-lowering of functions that should have been marked "never
instrument" may suddenly get instrumented. Instead of deciding at the front-end
whether to emit the attribute, we should instead handle the attribute in LLVM
IR properly in the back-end if we're emitting XRay instrumented binaries.</pre>
