Reland: "[WebAssembly] Add new pass to lower int/ptr conversions of reftypes" Add new pass LowerRefTypesIntPtrConv to generate debugtrap instruction for an inttoptr and ptrtoint of a reference type instead of erroring, since calling these instructions on non-integral pointers has been since allowed (see ac81cb7e6).

[WebAssembly] Implementation of global.get/set for reftypes in LLVM IR Reland of 31859f896. 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.
