852baabc17 heap: Add flag v8_enable_inner_pointer_resolution_osb 
This CL introduces a compile flag v8_enable_inner_pointer_resolution_osb
behind which lies the experimental implementation of the object start
bitmap. It disassociates the object start bitmap from the compile flag
v8_enable_conservative_stack_scanning. At the moment the former flag is
a prerequisite for the latter, as conservative stack scanning requires
some mechanism for inner pointer resolution and the object start bitmap
provides one such mechanism.

d39d75b5e9 [wasm][cleanup] Merge opcode names into main macros 
This merges the separate opcode name definitions from wasm-opcodes-inl.h
into the main opcode-defining macros in wasm-opcodes.h. This is simpler
(avoids a bunch of fairly complex macros) and easier to update when we
add new opcodes in the future.
The tests become obsolete because they would simply repeat the implementation.

481ad16db6 [wasm] Align OpcodeName() with spec for Atomics opcodes 
The names we returned in WasmOpcodes::OpcodeName(...) for Atomics opcodes
did not match the spec. This patch fixes that.
This matters in particular when we want to provide disassembly of
modules.

5696b52624 [utils] Introduce SparseBitVector 
We currently have a BitVector implementation which is used a lot by the
two (mid-tier and top-tier) register allocators. Their size is the
number of virtual registers or the number of blocks in the function. If
one of those numbers gets huge, the BitVector does not perform well any
more, and it consumes huge amounts of memory (we see up to several GBs
for huge Wasm functions).

This CL introduces a SparseBitVector implementation with a compatible
interface, meant to replace the BitVector implementation. Usages will be
introduced in follow-up CLs, first for the mid-tier allocator, then
top-tier. This will allow us to assess performance changes better, and
revert individual usages.

fa8c5950e0 [base] Introduce FormattedString 
This introduces a class which can be used for formatting dynamic values
into a constant-size, stack-allocated array. You get ostream-style code
but printf-style performance, and in particular no dynamic allocation.
This makes this class also suitable to be used in OOM or other fatal
situations where we cannot rely on dynamic memory allocation to still
work.

Using FormattedString will automatically compute the format string
depending on the types. It also computes the maximum size of the output.
Last but not least, it makes the code a lot more readable than
traditional printf style printing.

9e3f20b225 [test] Move cctest/test-log to unittests/logging/log-unittest 
This is a reland of https://chromium-review.googlesource.com/c/v8/v8/+/3607389.
The previous revert is https://chromium-review.googlesource.com/c/v8/v8/+/3610448.
Reason for revert: https://crbug.com/v8/12838.

The original CL has merge conflicts and cannot be relanded,
so this CL is newly opened.

This CL moves cctest/test-log to unittests/logging/log-unittest
, fixes the flaky tests in https://bugs.chromium.org/p/v8/issues/detail?id=12838 and updates the unittests status for log-unittest.


Flaky Tests:
- https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20TSAN%20-%20stress-incremental-marking/7287/overview
  - flaky LogTest.Issue539892 is caused by in stress-incremental-marking
    mode, Heap::MarkCompact will trigger CodeMovingGCEvent in https://source.chromium.org/chromium/chromium/src/+/main:v8/src/heap/heap.cc;l=2586;drc=52f06e6b43ff95eccf79e0a5df8d4d83c029130a for
    FakeCodeEventLogger which was already destructed
    when Heap::PerformGarbageCollection task was handled in
    DefaultPlatform::PumpMessageLoop. This should be fixed by removing
    FakeCodeEventLogger in LogTest.Issue539892.

  - flaky LogTest.LogAccessorCallbacks is caused by the data race in
    Sampler::DoSample. This should be fixed in https://chromium-
    review.googlesource.com/c/v8/v8/+/3616429.

-https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20TSAN/41327/overview
  - flaky LogTest.ExternalLogEventListenerWithInterpretedFramesNativeStack
    is caused by the data race of i::FLAG_* which were written again after
    setting up the isolate. This should be fixed by only writting
    i::FLAG_* before setting up the Isolate.

- https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64/47277/overview
  - flaky LogTest.BuiltinsNotLoggedAsLazyCompile is caused by the data
    race in Sampler::DoSample. This should be fixed in https://chromium-
    review.googlesource.com/c/v8/v8/+/3616429.
