4facbf213c [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.

cd460c4d11 [WebAssembly] Fixup order of ins variables for table instructions 
WebAssembly instruction arguments should have their arguments ordered from
the deepest to the shallowest on the stack.

69e2797eae [WebAssembly] Implementation of (most) table instructions 
Implementation of instructions table.get, table.set, table.grow,
table.size, table.fill, table.copy.

Missing instructions are table.init and elem.drop as they deal with
element sections which are not yet implemented.

Added more tests to tables.s
