SDAG: Implement Select instead of SelectImpl in WebAssemblyDAGToDAGISel

Browse Source 
This backend doesn't do anything custom here yet, so we just modernize
the boilerplate.

Part of llvm.org/pr26808.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@269506 91177308-0d34-0410-b5e6-96231b3b80d8
