OK, thanks for looking into it.
I think we'll mark this fixed then. If someone runs into the performance issue,
there are tons of workarounds: pass -fno-omit-frame-pointer, -mstackrealign,
-mstack-alignment=32, or whatever. Those all use a different codepath from
TargetOptions::StackAlignmentOverride, and should avoid the unaligned loads.</pre>
