f0289f00 - [Hexagon] Avoid contracting predicates in createHvxPrefixPred (#183081)

[Hexagon] Avoid contracting predicates in createHvxPrefixPred (#183081) The function createHvxPrefixPred should only need to expand a predicate to match the result's bytes-per-bit. Otherwise, contracting of the predicate may lead to an input that is shorter than 4 bytes, making it unsuitable for VINSERTW0. When calling createHvxPrefixPred for vector concatention, re-group the inputs to the concat to make sure that the resulting inputs to createHvxPrefixPred would not need contraction.
