After JDK-8353786, the "(sopc != 0)" in this condition is always true
https://github.com/openjdk/jdk/blob/ca7b885873712a5ae503cb82c915d709034a69f7/src/hotspot/share/opto/vectorIntrinsics.cpp#L386
because we would bail out here otherwise:
https://github.com/openjdk/jdk/blob/ca7b885873712a5ae503cb82c915d709034a69f7/src/hotspot/share/opto/vectorIntrinsics.cpp#L371

Same just after:
https://github.com/openjdk/jdk/blob/ca7b885873712a5ae503cb82c915d709034a69f7/src/hotspot/share/opto/vectorIntrinsics.cpp#L394
(except if arch_supports_vector takes sopc as non-const reference and modifies it, which seems unlikely)
