use correct longInt accessor in equality test

We incorrectly accessed the longLongIntValue_ section of the union when
comparing a lont int and an unsigned long long int.

This resulted in incorrect behavior on some 32bit platforms. This is
likely due to the union not being zero initialized.

Fix this by using the correct accessor, longIntValue_.
