Sanjay Patel 46b083ef4a [PatternMatch, InstSimplify] fix m_NaN to work with vector constants and use it
This is NFC for the moment (and independent of any potential NaN semantic
controversy). Besides making the code in InstSimplify easier to read, the
motivation is to eventually allow undef elements in vector constants to
match too. A proposal to add the base logic for that is in D43792.
