Previously both the length and the endColumn for Wasm scripts were reported as 0, and that was sort of okayish, since the front-end was ignoring both of these fields in case of Wasm, and was applying special cases. But these special casing lead to some subtle bugs, and this is the first step towards a more uniform treatment. Source positions for Wasm are in terms of the bytecode, and the column field contains the bytecode offset here, while the line number field is always 0. Hence we send 0 for both startLine and endLine as before, but endColumn now corresponds to the bytecode size.

To ensure that regexp syntax errors are reported as early errors, SpiderMonkey calls ParseRegExp at parse time to validate that the regexp parses properly. This does not require the allocation of named capture information. We have a project underway to completely eliminate the allocation of GC things at parse time, which will require us to suppress the allocation of named capture information (or else jump through hoops to implement FixedArray as a non-GC thing). We can work around this in our shim layer -- for example, by setting a flag on the Factory shim that causes us to allocate dummy objects -- but it's much simpler to add an option to ParseRegExp. (Note: V8 currently does not treat regexp syntax errors as early errors. See https://bugs.chromium.org/p/v8/issues/detail?id=896.)

Motivation: In the wasm-gc proposal, structs and arrays are allowed to store elements of packed types i8 and i16. Changes: - Add i8 and i16 to ValueType. - Fix all case switches to handle the new cases. - Add a couple helper methods to ValueType and improve the implementation/usage of a couple more.

We can do a good job of optimizing Torque expressions that load and check multiple bitfields from a bitfield struct, but only if those expressions are written using the binary `&` operator as opposed to the logical `&&`. This change adds a lint rule to detect some simple cases where we should clearly prefer `&` to `&&`.

VisitWord32EqualImpl was checking for inputs of type kCompressedHeapConstant, but it can also sometimes have inputs of type kHeapConstant. In either case, we can check for whether to do a load from the roots array. This improves Octane score by about 3% (or about 1.5% if --no-opt is specified).

This CL is a step towards reversing JS stack arguments for TurboFan. It does the following: 1. Add StackOrder to CallInterfaceDescriptor 2. Reverse arguments in TF backend for JS calls. 3. Cleanup TFJ builtins interface descriptors, since calls for these builtins already reverse the arguments, we don't need to reverse the interface descriptor anymore.

The latter is also linked directly from the wasm engine, and the engine is linked from the native module, to which the DebugInfoImpl already has access. Hence, this CL removes the redundant Isolate pointers, and just accesses the engine and the allocator via the NativeModule.
