Test gcc.target/arm/neon-vld1_dupQ.c started failing with r194594, a C front end change that causes the test to get warnings. The test passes local variables of type int64x1_t to functions declared with arguments of type int64_t. This patch casts the values passed to those arguments. It's possible that the patch invalidates the intent of the test, so I've copied the test's author.
OK for trunk? Janis
