[TableGen] Handle ValueType in CodeGenDAGPatterns GetNumNodeResults
A ValueType in a pattern dag is a type cast, and GetNumNodeResults should
handle it (the type cast has only one result).
This comes up, for example, during the type checking of pattern fragments, for
example, AArch64's Neon_combine_2d fragment is:
dag Operands = (ops node:$Rm, node:$Rn);
dag Fragment = (v2f64 (concat_vectors (v1f64 node:$Rm), (v1f64 node:$Rn)));
