When global object has proxies we should first call hasProperty and then call SetProperty if has property returns true. This cl fixes both StoreGlobal and StoreLookupGlobal to correctly handle these cases.

{AsyncCompileJob::FinishCompile} sometimes takes a long time, especially if DevTools is open. A lot of time can be spent making the script(s) available to DevTools, or executing the {CompilationResultResolver}.

The {TurboAssembler} already has logic to use the {lzcnt} and {tzcnt} instructions if available, and otherwise falls back to a slightly optimized variant of the previous code. Thus, we just call these methods. Drive-by: Use {movl} instead of {Set} for constant values, for consistency, readability and performance.

Add information to CallInterfaceDescriptor if additional implicit arguments can be passed on the stack, that is, if it is a varargs calling convention. With this information, we can have a proper DCHECK in CSA to avoid passing the wrong number of arguments to builtins that don't support it. Previously, this lead to difficult to investigate crashes with misaligned stacks. Drive-by cleanup: Reduce duplication between DEFINE_PARAMETERS_... macros.

Port b875f466 Original Commit Message: This is a reland of 4a16305b The original CL adjust only one part of the stack check, namely the comparison of the stack pointer against the stack limit in generated code. There is a second part: Runtime::kStackGuard repeats this check to distinguish between a stack overflow and an interrupt request. This second part in runtime must apply the offset just like in generated code. It is implemented in this reland by the StackCheckOffset operator and a new StackGuardWithGap runtime function. Original change's description: > [compiler] Optionally apply an offset to stack checks > > The motivation behind this change is that the frame size of an optimized > function and its unoptimized version may differ, and deoptimization > may thus trigger a stack overflow. The solution implemented in this CL > is to optionally apply an offset to the stack check s.t. the check > becomes 'sp - offset > limit'. The offset is applied to stack checks at > function-entry, and is set to the difference between the optimized and > unoptimized frame size. > > A caveat: OSR may not be fully handled by this fix since we've already > passed the function-entry stack check. A possible solution would be to > *not* skip creation of function-entry stack checks for inlinees. > > This CL: 1. annotates stack check nodes with the stack check kind, where > kind is one of {function-entry,iteration-body,unknown}. 2. potentially > allocates a temporary register to store the result of the 'sp - offset' > in instruction selection (and switches input registers to 'unique' > mode). 3.
