s6.2.1, seems to say "Implicit conversions between built-in vector data types are disallowed." though. But considering that we disallow functions without a prototype. It should be fine.

However, is there any way to construct a test for this? Could it be tested similarly to https://reviews.llvm.org/D55023?
