Part of D105020 <https://reviews.llvm.org/D105020>. Also, fixed FIXMEs that need to use wider vector type
when trying to calculate the cost of reused scalars. This may cause
regressions unless D100486 <https://reviews.llvm.org/D100486> is landed to improve the cost estimations
for long vectors shuffling.
