D155929 <https://reviews.llvm.org/D155929> teach lowerScalarInsert to handl start value (extractelement scalable_vector, 0)
and specifically converts fixed extracted vectors to scalable vectors when
lowering vector reduction. It's not enough because there is another way to
create (extractelement fixed_vector, 0) as a start value of lowerScalarInsert
like #64327.
