- Renames StackParameterCount to ParameterSlotCount, to avoid confusion between slots and parameters, which are not in general equivalent. - Similarly, renames StackReturnCount to ReturnSlotCount. - Adjusts the result of GetFirstUnusedStackSlot to return one more than the last slot of the argument area, not including padding. - Renames GetFirstUnusedStackSlot to GetOffsetToFirstUnusedStackSlot to reflect that the result is an offset from callee to caller frames. - GetReturnsOffset is a little clearer, with adjustment for the different semantics of GetFirstUnusedStackSlot. - Renames 'optional_padding_slot' and 'first_unused_stack_slot' variables in Tailcall codegen to reflect that these are offsets.

This CL removes wasm-js.cc from compilation if v8_enable_webassembly=false. In order to do so, an alternative implementation of {v8::WasmStreaming} has to be provided, because the public API should stay unchanged. The only path to obtain a {v8::WasmStreaming} object is via {v8::WasmStreaming::Unpack}, which will always fail if WebAssembly is not supported. Hence all methods in {WasmStreamingImpl} are unreachable. As a drive-by, this CL removes all includes from src/wasm in src/init (bootstrapper.cc would have been done anyway, and v8.cc is just a few changes).

This removes the {wasm_engine_} field from the isolate if v8_enable_webassembly=false. This avoids any includes from src/wasm in isolate.{h,cc}. Unconditional access to the wasm engine in other parts are also #if'ed out to avoid nullptr accesses. Long-term, the {Isolate::wasm_engine()} method will be fully removed, but this can only be done once src/wasm is excluded from compilation.

This CL generalized the previous check that a FunctionTemplateInfo instance is not changed after being instantiated to a check for immutability after being published. A FTI is considered published once it is instantiated (set in a SharedFunctionInfo) or set as an accessor on a JSObject. The published state is tracked in the flags field. TurboFan relies on this immutabilty for concurrent access. The immutability requirement was already met before this CL, but this change enforces this by adding necessary checks.

This adds the possibility to define non-nullable function tables of heap types kFunc and user-defined functions. When such table is defined, it is obligatory to provide an initializer expression after its limits. Currently, this can only be a function reference. Changes: - Change WasmTableObject::raw_type to encode the whole entry type. - Restructure call_indirect to load the signature only if needed, and do null checks only if needed. - Add the requirement to provide an initializer expression for non-nullable tables in module-decoder. - Rename "global initializer" -> "initializer expression" everywhere. - Add table initialization in module-instantiate. - Edit both the C++ and JS WasmModuleBuilder. - Add and slightly improve tests. - Format wasm-module-builder.js.

Also add a V8_COMPRESS_POINTERS_IN_SHARED_CAGE define when pointer compression is enabled. This CL is to get performance numbers for reserving an extra register. There is no actual pointer cage yet, and the base register will always have the same value as the root register. The pointer decompression code is switched to using the base register instead of the root register.
