My latest post summarizes the status of trimming target specific intrinsics here: https://discourse.llvm.org/t/rfc-compress-intrinsic-name-table/82412/49

Its either illegal or has high logistical cost. And since code size savings seems to be not significant from that change, this one (whose motivation was an even smaller data size savings) seems even less significant to pursue. So I am planning to close this and other reviews once the thread settles down. I have minor turly NFC improvement, which I'll implement sometime soon.
