The DotProductQuadruple methods are currently defined on Int8 vectors. There are some problems for that. 1. We defined a DotProductQuadrupleSaturated method, but the dot product part does not need saturation, as it cannot overflow. It is the addition part of VPDPBUSDS that does the saturation. Currently we have optimization rules like x.DotProductQuadrupleSaturated(y).Add(z) -> VPDPBUSDS which is incorrect, in that the dot product doesn't do (or need) saturation, and the Add is a regular Add, but we rewrite it to a saturated add. The correct rule should be something like x.DotProductQuadruple(y).AddSaturated(z) -> VPDPBUSDS 2. There are multiple flavors of DotProductQuadruple: signed/unsigned × signed/unsigned, which cannot be completely disambiguated by the type. The current naming may preclude adding all the flavors. For these reasons, remove the methods for now. We can add them later with the issues addressed.
