This patch adds TargetStackID::WasmLocal. This stack holds locations of values that are only addressable by name -- not via a pointer to memory. For the WebAssembly target, these objects are lowered to WebAssembly local variables, which are managed by the WebAssembly run-time and are not addressable by linear memory. For the WebAssembly target IR indicates that an AllocaInst should be put on TargetStackID::WasmLocal by putting it in the non-integral address space WASM_ADDRESS_SPACE_WASM_VAR, with value 1. SROA will mostly lift these allocations to SSA locals, but any alloca that reaches instruction selection (usually in non-optimized builds) will be assigned the new TargetStackID there. Loads and stores to those values are transformed to new WebAssemblyISD::LOCAL_GET / WebAssemblyISD::LOCAL_SET nodes, which then lower to the type-specific LOCAL_GET_I32 etc instructions via tablegen patterns.
