This change is needed for profiling of Wasm code that calls C-function to ignore the C-stack above the Wasm stack that otherwise couldn't be parsed otherwise.

This extends the debug side table to also store register locations in addition to constants and stack values. Previously, every value that was not constant was assumed to be spilled to the stack. This made sense, because without breakpoints we would only emit debug side table entries at call sites, where all registers are spilled. With breakpoints, this changes. At break locations, values might be live in registers. The logic to decide whether a value will live in the register or on the stack is extended, because we sometimes generate the debug side table entry at a point where the registers are not spilled yet. The debug side table entry creation needs to account for that, and assume that these registers will still be spilled.

GCC emits a stringop-truncation warning because set_name() uses the entire buffer for strncpy(). This looks potentially unsafe, though set_name() does the right thing and add a NUL terminator immediately after strncpy() finishes. To make GCC happy, reduce the number of characters copied by 1.

After support for ARCH_PPC was dropped, it became a subset of ARCH_PPC64. If you compile for ppc64, then you set the ARCH_PPC64 define which also sets the ARCH_PPC define. To be able to again support ppc (32 bit) those defines should be split up again. This commit only splits up the defines but does not introduce a working ARCH_PPC variant.

This is important, because for code without breakpoints, we generate the debug side table lazily via the {GenerateLiftoffDebugSideTable} method, and it needs to match the code generated previously via {ExecuteLiftoffCompilation}.

This is the first piece of the wasm debugging prototype (besides the changes to add/remove breakpoints in WasmModuleObject made with https://chromium.googlesource.com/v8/v8.git/+/e699f39caed9a23f8e20bd3a0386a3236e272737). This changelist adds the infrastructure for a GDB-remote stub that will be used to manage debugging sessions via the gdb-remote protocol. It enables the creation and termination of debugging sessions over TCP connections that are managed in a separate thread. The logic to actually send, receive and decode GDB-remote packets will be part of a future changelist. Build with: v8_enable_wasm_gdb_remote_debugging = true Run with: --wasm-gdb-remote Enables Wasm debugging with LLDB (default: false) --wasm-gdb-remote-port TCP port to be used for debugging (default: 8765) --wasm-pause-waiting-for-debugger Pauses the execution of Wasm code waiting for a debugger (default: false) --trace-wasm-gdb-remote Enables tracing of Gdb-remote packets (default: false) Note that most of this code is "borrowed" from the code of the Chromium NaCL GDB-remote stub (located in Chromium in src\native_client\src\trusted\debug_stub). Implementation details: - class GdbServer acts as a singleton manager for the gdb-remote stub. It is instantiated as soon as the first Wasm module is loaded in the Wasm engine. - class GdbServerThread spawns the worker thread for the TCP connection. - class Transport manages the socket connection, in a portable way. - class Session represents a remote debugging session. - class Target represents a debugging target and it’s the place where the debugging packets will be processed and will implement the logic to debug a Wasm engine.

This refactors the debug side table such that we can easily add register information later. In particular - vectors for types and stack offsets are combined into one; - constants are stored in the same vector; - locals and operand stack values are stored in the same vector. A follow-up CL will extend the DebugSideTable to also encode locals or operand stack values held in registers.

This fully tnodifies TryHasOwnProperty, TryLookupProperty, CheckPrototypeEnumCache, CheckEnumCache and ExtractFixedDoubleArrayFillingHoles. CopyElementsOnWrite is also converted except for parameters passed with ParameterMode. Also fixes the type of TryLookupProperty, which fails tests if the object parameter is actually forced to be JSReceiver.

Different loggers had different logic to handle unnamed wasm functions. This CL makes sure that we always set a reasonable name when logging wasm code, and removes handling for unnamed code in individual loggers. Since logging only happens on user action, the code is not optimized for performance (i.e. we always just write to a {std::string}, even if the length of the string is known to be limited).
