[SLP]Do correct signedness analysis for externally used scalars
If the scalars is used externally is in the root node, it may have
incorrect signedness info because of the conflict with the demanded bits
analysis. Need to perform exact signedness analysis and compute it
rather than rely on the precomputed value, which might be incorrect for
alternate zext/sext nodes.
Fixes #113520

Have to compare actual type size to pick up proper cast operation
opcode.
