It's fairly difficult.  You want a way to turn off specific warnings
for specific parts of the IR.  The IR is combined and rearranged
during optimization, so you need to figure out how to make the warning
control track those changes.

There was some recent discussion of this on the gcc-patches mailing
list.  Look for __nowarn__.
