[InstSimplify] fix potential miscompile in select value equivalence

This is the sibling fix to c590a9880d7a -
as there, we can't subsitute a vector value the equality
compare replacement that we are trying requires that the
comparison is true for the entire value. Vector select
can be partly true/false.
