+Subject: [PATCH 20/29] run-pass/const-endianness: negate before to_le()
+
+`const LE_I128` needs parentheses to negate the value *before* calling
+`to_le()`, otherwise it doesn't match the operations performed in the
+black-boxed part of the test.  This only makes a tangible difference on
+big-endian targets.
