This CL improves the parsing and validation speed of WASM bytecode by eliminating a call to get the "simple opcode signature" on the fast path. It introduces a byte-indexed array that points directly to a FunctionSig*. By declaring the array in the wasm-opcodes.h header file and initializing (constexpr) in the wasm-opcodes.cc file, the decoder can use this array directly in its first test. (Note that constexpr obviates the need for LazyInitialize in previous iterations of this mechanism). There are two more calls on this fast path that can be simplified, WasmOpcodes::IsSignExtensionOpcode() and WasmOpcodes::IsAnyRefOpcode(). These calls are needed to check for a feature flag and can be implemented differently in a followup CL.

This CL adds support for "secondary parameter locations" for the WASM instance parameter. Since this parameter is spilled onto the stack by the function prologue, it is not necessary to allocate additional spill slots for it. This saves both code space and runtime.

This loads references to {null} values from the instance object instead of embedding them into the generated code. It is one step towards making the {WasmCode} objects independent of the Isolate. Note that this also fixes an issue with the serializer/deserializer that failed to properly serialize {null} values and accidentally collapsed them to {undefined} values instead.
