Reland of 31859f896 <https://reviews.llvm.org/rG31859f896cf90d64904134ce7b31230f374c3fcc>.

This change implements new DAG notes GLOBAL_GET/GLOBAL_SET, and
lowering methods for load and stores of reference types from IR
globals. Once the lowering creates the new nodes, tablegen pattern
matches those and converts them to Wasm global.get/set.
