I'll comment this here in case it's relevant: this patch is adding support for `#dbg_value` to SROA, but doesn't add it for `llvm.dbg.value`. Maybe that's fine, since we're moving from intrinsics to records and already use records by default, so we don't need to include intrinsics in every new patch; just noting that if you intend to make use of debug intrinsics downstream, you'll need to add support for `DbgValueInst` in the same way you have for debug value records.
