8269179: Crash in TestMacroLogicVector::testSubWordBoolean: assert(_base >= VectorMask && _base <= VectorZ) failed: Not a Vector

Hi all,

compiler/vectorization/TestMacroLogicVector.java crashed on AVX512 machines.

Here is the symptom and stack trace:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (/jdk17/src/hotspot/share/opto/type.hpp:1717), pid=19546, tid=19562

The reason is that for vpternlog_mem, n->in(1) points to BinaryNode.
This is incorrect since BinaryNode->bottom_type() returns Type::BOTTOM.
So it should be something like n->in(1)->in(1).

Thanks.
Best regards,
Jie
