Subject: [PATCH] Suppress sizeof-array-div warnings in thrust found by gcc-11
 (#10840)

`sizeof-array-div` is a new warning added in gcc-11 and thrust 1.15 will trigger it when a `T` type is a fixed size array. Nothing is wrong with the thrust logic, so we just suppress the warning while we wait on thrust 1.16
