Consider case where `__int128` type is supported by the host target but not by a device target (e.g. spirv*). Clang emits an error message for unsupported type even if the device code does not use it. This patch fixes this issue by emitting the error message when the device code attempts to use the unsupported type. Reviewed By: tra Differential Revision: https://reviews.llvm.org/D111047
