AARCH64 Code Size regression between 6/7
I did a bit more poking, using llvm/clang versions 6-8. The IR in all
cases appears fundamentally identical. I ran the IR generated by version 6
through llc on all three versions. llc-7/8 produced the extra ADRPs, llc-6
did not. So (to my untrained eyes), the IR is generated the same, it is in
the IR->AARCH64 asm pass that the extra instructions are being generated.
