This fixes issues with replacing the return address of deeper (non-top) wasm frames, i.e. frames which are at a call position. The replaced address should also point after the call in the new code, so we don't execute the same call again. This is achieved by using slightly different encodings for breakpoint positions and other (wasm instruction) positions. Breakpoints set {is_instruction} to {false} in the source position table entry, whereas usual wasm instruction set it to {true}. Also, during stack walking for OSR, we remember whether we want to OSR to the position before the instruction (if it's the top frame), or after the call instruction (if it's deeper in the stack). We then use the {is_instruction} predicate to find the right location.

Rework the testMemoryGrowReadWrite and testMemoryGrowZeroInitialSize tests. Combine the different sized tests (32, 16, 8 bit integers) into a single base tests, taking in function arguments to specify which load/store function to call from the module exports. Also reduced the number of checks made in each test. Previously the test was asserting on every single valid offset. Now it checks the first 5 and the last 5 of each page of memory. From a quick local test using `time`, it speeds up this test on x64 from ~40s to ~20s. There is more work to be done: there are other tests below that also assert on each offset, we can change those in a future patch. The goal is to be able to run this on arm simulators sufficiently quickly, and not require to mark this test as slow.

GCInfo and its related infrastructure is used to record information about types. Currently, we store finalization and vtable information. Future changes will introduce naming and tracing, similar to Oilpan in Blink. Information is stored in a process-wide global table that is maintained at runtime. For static builds such information can be recorded in the binary without the runtime overhead which is future work. This ports `third_party/blink/renderer/platform/heap/gc_info.{h,cc}` on a semantic level. In addition to adjusting to V8's needs, we also re-commit the already filled parts of the info table as read-only when possible, making it harder to override type information.

This DCHECK can fail because we currently pass arbitrary types in the typer unittests. Changing the tests is complicated by the fact that the compiler makes heavy use of type Any and we don't want to lose test coverage for that. Hence for now I just remove the DCHECK. I'm working on a follow-up CL but that one will not be able to land any time soon due to the current restrictions.

"By my deeds I honor him. V8." - Add basic build files for library and unittests. - Integrate unittests also in existing V8 unittests for simplicity. The CL also adds FinalizerTrait and unittests to allow building a testing target that executes code. FinalizerTrait is used to determine how managed C++ types are finalized. The trait should not be overridable by users but needs to be exposed on API-level to avoid including library-internal headers.

We previously could not OSR a frame paused in a breakpoint with another frame in which the same breakpoint was removed, because the latter was missing the source position.

This CL implements this by an explicit check on each br_on_exn (within {GetExceptionTag}). This check will be redundant if several br_on_exn follow each other. Since also the runtime call for {GetExceptionTag} is redundant, and also the fact that we do a runtime call is suboptimal, I consider the whole implementation prototypical for now anyway.

On Linux, Perfetto translates the builtin "ts" timestamp in trace event from CLOCK_MONOTONIC to CLOCK_BOOTTIME, before passing them to devtools. Devtools therefore implicitly operates on timestamps that are in CLOCK_BOOTTIME. However, additional timestamps sent in trace event payload arguments will not be converted to CLOCK_BOOTTIME by Perfetto, raising the possibility of devtools using timestamps from multiple clock domains incorrectly. Since trace events sent by CpuProfile also include the builtin "ts" trace timestamp (sampled from CLOCK_MONOTONIC nearly at the same time by the tracing framework), sending "data.startTime" and "data.endTime" is essentially redundant. devtools-frontend:2113957 stops the use of the value of these timestamps in the payload of Profile and ProfileChunk events. Devtools continue to use the presence of these arguments to indentify start and end profile events. ProfileChunk events also include "timeDeltas" which are relative timestamps. They are also in CLOCK_MONOTONIC and are not translated by Perfetto. devtools-frontend:2113957 computes absolute CLOCK_BOOTTIME timestamps from timeDeltas by adding them to "ts" in the "Profile" event (previously, "data.startTime" was used). This is only valid if the system is not suspended/resumed during profiling. Providing support for suspend/resume in the middle of profiling will likely involve having Perfetto convert "timeDeltas" directly to CLOCK_BOOTTIME. This CL introduces no code changes and only adds comments to explain the above.

If we do that, whenever we advance to the next bytecode we don't have to advance to the next literal bytecode, but instead "advance" in the sense of doing the JumpLoop. Adding tests that test this advancing for wide and extra wide JumpLoops. Also, marking JumpLoop as needing source positions since now it has the ability of causing an interrupt.

Introduces a new macro BUILD_V (v is for vector) that pushes bytes into a vector (instead of directly in an array initializer, see BUILD). This has the positive effect of being able to handle opcodes of multiple bytes (e.g. SIMD opcodes bigger that 0xfd80). Because of this "API" change, our helper macros in test-run-wasm-simd.cc and wasm-run-utils.h need to change too. So, we introduce new macros (suffixed by _V), that will call the appropriate lambdas defined in BUILD_V, that knows how to push bytes into the vector, and also can handle multi-byte opcodes. This design has a bit of duplication and ugliness, but was chosen to reduce the impact of existing tests. No restructuring of test code is required, we only need to add suffix _V. Note that we do not have multi-byte opcodes yet (in wasm-opcodes.h), this change will be breaking, and requires all the tests to be updated to use _V macros first.
