Good catch. Thank you for the fix.

 TARGET_BUILTIN(__nvvm_match_any_sync_i32, "UiUiUi", "", PTX60)
-TARGET_BUILTIN(__nvvm_match_any_sync_i64, "WiUiWi", "", PTX60)
+TARGET_BUILTIN(__nvvm_match_any_sync_i64, "UiUiWi", "", PTX60)
 // These return a pair {value, predicate}, which requires custom lowering.
----------------
I've also noticed that the PTX spec also says `Requires sm_70 or higher.`, so we may want to fix the constraint, too.
