The regexp stack is used during execution of jitted regexp matcher code. Previously, the stack was initially not present / nullptr, and we had to explicitly check for this condition and bail out in builtin code. This CL changes behavior to guarantee a present stack by adding a statically-allocated area that is used whenever no dynamically-allocated stack exists.

They have no function and are confusing to first time users, who think that you have to click that to upload a file.

With the recent removal of the --wasm-shared-code flag, it became effectively impossible to turn off this flag. Hence its functionality became mandatory and the ability to turn off sharing of {WasmEngine} process-wide has to be removed as well.

Port a8cdda99 Original Commit Message: WebAssembly locals are specified to be zero on function entry. Liftoff implements this by just storing the constant 0 in the virtual stack for integer types, and using one floating point register initialized to zero for all floating point types. For big counts of locals this leads to problems (manifesting as huge blocks of code being generated) once we hit a merge point: All those constants (for int) and all duplicate register uses (for floats) need to be fixed up, by using separate registers for the locals or spilling to the stack if no more registers are available. All this spilling generates a lot of code, and can even happen multiple times within a function. This CL optimizes for such cases by spilling all locals to the stack initially. All merges within the function body get much smaller then. The spilled values rarely have to be loaded anyway, because the initial zero value is usually overwritten before the first use. To optimize the code size for initializing big numbers of locals on the stack, this CL also introduces the platform-specific {FillStackSlotsWithZero} method which uses a loop for bigger local counts. This often saves dozens of kilobytes for very big functions, and shows an overall code size reduction of 4-5 percent for big modules.

Symbol and *String classes are now declared on Torque with generateCppClass, which means they don't use macro accessors anymore. As such, the gen-postmortem-metadata script is not able to automatically detect fields for those classes. Define metadata for those fields manually for now. In the future we might want to generate it from Torque for consistency. Also renamed a few *String fields metadata to match the expected format (className__fieldName__fieldType).

DCHECKs are not really special, they just create a non-constexpr path within an otherwise constexpr function. Since C++14, this is allowed.

This fixes a bug where coverage for the inline script <script>function foo() {}<script> started to get deterministically reported as covered after crrev.com/c/1771776, while before it, we most of the time reported it as uncovered (depending on heap order of SFIs). The correct result is to report `foo` as uncovered as it is never called. The problem arose from the fact that v8:9212 needed to handle extra-wrappers around scripts correctly. Those wrappers have the same source range as the wrapped script and a call count of zero even if the wrapped script is executed. To filter them out, we previously determined nesting for identical source ranges by ascending call count. However, in the script case above, the script has call count one, while `foo` (which has the same source range) has call count zero. In this case, nesting is decreasing order of call counts. This CL is a minimal change that sorts SFIs which are top-level to the front, only then considers call counts in descending order. This preserves the behavior that node's extra wrappers are sorted to the front (and then filtered out by existing logic), but also ensures that for the example above, we report the script's coverage before the coverage for `foo`.

Remove the native context slot from contexts by making context maps native-context-specific. Now we require 2 loads to go from a context to the native context, but we have 1 field fewer to store when creating contexts.

The tests were already passing because they happened to use objects allocated in the lower half of the heap reservation, but this small change should make behavior more consistent.

We currently generate code for both separately, resulting in five instructions (three for the i32_eqz, two for the br_if): test rax,rax seteq dl movzxb rdx,rdx test rdx,rdx jz <label> After this CL, we just generate two instructions: test rax, rax jnz <label> This is implemented by a look-ahead in the {kExprI32Eqz} handler. If the opcode is followed by {kExprBrIf}, no code is emitted. Instead, a flag in the {LiftoffCompiler} is set to signal to the {kExprBrIf} handler that the previous instruction was not processed yet. Note that this mechanism is designed to be reusable for more similar improvements. For the single instance implemented in this CL, it is not needed. Plus some drive-by cleanup.
