Following up on https://crrev.com/c/2689185, this CL significantly simplifies the whole implementation of the stack trace capturing. Before this CL, capturing any stack trace (for the purpose of the API or Error.stack) would roughly work like this: 1. The CaptureStackTrace() function uses the StackFrameIterator to walk the system stack. For each native frame it uses the FrameSummary abstraction to get all (including potentially inlined) frames. For each of those it appends a record consisting of six elements to a FrameArray (this holds pointers to the actual closures and receivers). 2. Afterwards the FrameArray is shrinked to the required size, and a new FixedArray is allocated, and initialized with new StackTraceFrame objects where each holds a reference to the FrameArray, the index of the frame, and an initially uninitialized StackFrameInfo reference. This new FixedArray is then returned from CaptureStackTrace() and either stored on a message object or provided to the API as v8::StackTrace. The new approach removes a lot of the machinery in between and directly creates a FixedArray of StackFrameInfo objects in CaptureStackTrace(). These StackFrameInfo objects are directly exposed as v8::StackFrame on the public API, and they hold the six fields that were previously stored flat in the FrameArray. This not only avoids a lot of copying around of data and creation of temporary objects and handles, but most importantly unifies and simplifies the stack frame function inside StackFrameInfo, so you no longer need to wonder which function / object might be responsible for a certain API. There's still a lot of room for improvement. In particular we currently don't cache the source position for a given StackFrameInfo (or globally), but rather recompute it every time. This is still very fast, significantly faster than the previous approach. There are some notable (potentially user visible) changes: - The CallSite#GetPosition() method now consistently returns the Wasm module relative bytecode offset for all Wasm frames (previously it'd return the function relative bytecode offset for non-asm.js Wasm frames). - The column and line numbers returned from StackFrameInfo methods are consistently 1-based now, instead of sometimes being 0-based (Wasm) and sometimes being 1-based (JS and asm.js Wasm). The only potentially noticable difference is that for CallSite#GetLineNumber() no longer returns 0 for Wasm frames, but that was wrong and useless anyways. - CallSite#GetThis() would sometimes return the_hole, another bug flushed out by this CL. The CL also contains some other not noteworthy drive-by-cleanups.

Ensure that epilogues are added to the LocalHeap before starting the GC. Adding the epilogue after invoking NotifyStarted() might mean that the epilogue is only added after the GC is already done and the epilogue isn't run at all. The test flakily fails because the epilogue didn't execute then.

Torque generates runtime accessor member functions for most class fields that are defined in .tq files, but fields with struct types are currently omitted. This change adds those accessors. As an example, if a .tq file defines the following: struct InternalClassStructElement { a: Smi; b: Smi; } class InternalClassWithStructElements extends HeapObject { const count: Smi; entries[count]: InternalClassStructElement; } Then the following accessors are generated to get and set each struct field within the 'entries' field: inline int entries_a(int i) const; inline void set_entries_a(int i, int value); inline int entries_b(int i) const; inline void set_entries_b(int i, int value); Bug: v8:7793 Change-Id: Ia40b5918e9d09f53ad8e78bc33f8629b8d6a79fe Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2676926Reviewed-by: -

In the latest spec, catch can take an exception index immediate, and control-flow jumps to the appropriate catch handler depending on the thrown exception. Do this by allowing multiple jump targets for the same pc in labels and in the control transfer map. At runtime, the unwinder will choose the appropriate control transfer entry based on the exception tag, unpack the exception and jump to the handler. Enable the exception cctests that were currently disabled for the interpreter, fix some issues and add tests for the new behaviors.

WrapperDescriptor is used to describe how JS wrapper objects can be inspected to find C++ wrappable objects. In addition, to specifying which embedder fields are used to find type and instance, the descriptor also provides and embedder id that identifies garbage-collected objects. It is expected that the first field of the type is a uint16_t with that id.
