I'm fairly sure that G_GLOBAL_VALUE used to fallback onto SelectionDAGISel, and 
that was changed in D78465 <https://reviews.llvm.org/D78465>. Because we only 
implemented the custom `adrp+movk` lowering in SelectionDAGISel, making that 
instruction sequence no longer fallback, so we don't get our proper lowering 
for HWASan globals.
