Linq: short and sbyte parameters fail for constant on Where expressions

The following fails using the CQL expression visitor, when the parameter is constant:

It does not fail when the parameter is a field:

The underlying cause is that the expression tree generated by the runtime is:

• For the first case, a binary expression containing a constant value on the right side of type int32 (instead of int16).

• For the second case, a binary expression containing a unary expression on the right side wit h a int16 operand.
