  [SDAG] Remove noundef workaround for range metadata/attributes (#141745)

In https://reviews.llvm.org/D157685 I changed SDAG to only transfer
range metadata to SDAG if it also has !noundef. At the time, this was
necessary because SDAG incorrectly propagated poison when folding
logical and/or to bitwise and/or.

The root cause of that issue has since been addressed by
https://github.com/llvm/llvm-project/pull/84924, so drop the workaround
now.
