These instructions should always treat inputs as signed, and saturate to unsigned min/max values. E.g. given -1, it should saturate to 0. The spec text, https://github.com/WebAssembly/simd/blob/master/proposals/simd/SIMD.md#integer-to-integer-narrowing, has been updated to describe this. The changes here include codegen changes to ia32, x64, arm, and arm64, changes to arm simulator, assembler, and disassembler to handle the case of treating input as signed and narrowing to unsigned. The vqmovn instruction can handle this case, our assembler wasn't allowing callers to specify this. The interpreter and scalar lowering are also fixed with this change.

Spill/fill now take offsets instead of indices. We provide a helper, GetStackOffsetFromIndex, for callers. This is currently only useful while slot sizes are still fixed to 8 bytes. StackTransferRecipe's RegisterLoad now works in terms of offset. LiftoffStackSlots work in terms of offset as well. TransferStackSlot currently still works in terms of indicies, but can be converted to use offsets in a subsequent change.

This is part 3 of Torquifying DescriptorArray: making it possible to use the "descriptors" indexed field from code written in Torque. A small macro EnsureArrayLengthWritable is converted to demonstrate the new functionality. This CL also introduces the arrow token `->` and desugars a->b to (*a).b so that the new builtin looks a little cleaner.

This reduction relies on a known object layout of the regexp instance in order to access the lastIndex field through a statically-determined offset. Prior to this CL, we checked only for instance types, not for the map, and thus it was possible to read garbage from either inside or outside the current object.

This CL implements torque builtins for BigInt subtraction and extends the compilation pipeline to lower calls to the generic subtraction to SpeculativeBigIntSubtract and later to BigIntSubtract with necessary checks in case of BigInt feedback. The CL also implements lowering of these operators to native machine word operations on 64 bit architectures if they are used in a truncating context (aka BigInt.asUintN).

For arm64 decompressing a TaggedSigned results in a 64-bit value, with the top 32 bits zeroed and the lower 32 bits being the SMI. This patch, with the --debug-code flag enabled, will corrupt the top 32 bits to try and catch places that are using 64-bit operations instead of 32-bit operations.

In most cases where we bail out to TurboFan, we actually have a fallback that just calls a C function instead. This fallback did not exist initially, but was added later for other platforms (see e.g. https://crrev.com/c/1044187). By reusing that fallback on intel, we remove another portion of function that could not be compiled in Liftoff on specific CPUs.

Individual frames of a stack frame in the frame cache might point to the JSFunction of that corresponding stack frame. It is illegal to serialize JSFunction objects in the isolate snapshot, so the attempt to serialize the stack frame cache results in a crash. This can happen when a warmup script is run, before a snapshot is created. This CL fixes the crash by not utilizing the stack frame cache in case the serializer is enabled.

We recently extended function-entry stack checks by an offset representing the difference in optimized and unoptimized frame sizes, with the intent of avoiding stack overflows during deopts. Although the generated code is very efficient (just a single additional register subtraction, executed exactly once per call), perf impact is measurable. To avoid the overhead in most cases, this CL adds a stack slack, currently set to 256 bytes, by which deopts are allowed to exceed the real V8 stack limit. For function-entry stack checks with an offset less than stack slack, the offset is not applied and the more efficient version of the stack check is emitted. The V8 limit is chosen to be smaller than OS stack size (assumed to be at least 1 MB). This guarantee is upheld even with slack.

We detect a stepping in Wasm from Javascript into Wasm then prepare the target function for debugging. The trick is redirect the target to interpreter and set a 'fake' breakpoint in the first instruction. Currently we don't need to clear this 'fake' breakpoint since it won't notify unless user intend to step in.

Port 63dc5556 Original Commit Message: A window is a Blink concept. This API marks the context as backing a detached window. This doesn't necessarily mean that the context is detached. Every time a JS function is called within a context that has a non-zero DetachedWindowReason, Runtime::kReportDetachedWindowAccess is invoked, which will report this call to Blink via a callback, which in turn can report number of such calls via UKM metrics.
