Original commit message:
[base] add build flag to use MADV_DONTFORK
Embedders like Node.js and Electron expose fork(2)/execve(2) to their
users. Unfortunately when the V8 heap is very large, these APIs become
rather slow on Linux, due to the kernel needing to do all the
bookkeeping for the forked process (in clone's dup_mmap and execve's
exec_mmap). Of course, this is useless because the forked child thread
will never actually need to access the V8 heap.
Add a new build flag v8_enable_private_mapping_fork_optimization which
marks all pages allocated by OS::Allocate as MADV_DONTFORK. This
improves the performance of Node.js's fork/execve combination by 10x on
a 600 MB heap.

Original commit message:
[wasm] Fix deadlock in async wrapper compilation
If compilation is cancelled while wrapper compilation is running, the
tasks spawned for the {AsyncCompileJSToWasmWrapperJob} will return
immediately, but {GetMaxConcurrency} will still return a positive
value. Hence {Join()} will spawn another task, resulting in a
livelock.
We could fix this by checking for cancellation in {GetMaxConcurrency},
but that requires taking the compilation state lock.
So this CL fixes the issue by dropping the number of outstanding
compilation units by to (basically) zero. We can't unconditionally drop
to zero because another thread might concurrently execute a wrapper
compilation and still call {CompleteUnit} afterwards. Hence only drop
outstanding units by the amount of not-yet-started units.

Original commit message:
Add option to report discarded allocations in sampling heap profiler
A couple of customers have asked about using devtools to get information
about temporary allocations, with the goal of reducing GC time and/or
peak memory usage. Currently, the sampling heap profiler reports only
objects which are still alive at the end of the profiling session. In
this change, I propose adding configuration options when starting the
sampling heap profiler so that it can optionally include information
about objects which were discarded by the GC before the end of the
profiling session. A user could run the sampling heap profiler in
several different modes depending on their goals:
1. To find memory leaks or determine which functions contribute most to
steady-state memory consumption, the current default mode is best.
2. To find functions which cause large temporary memory spikes or large
GC pauses, the user can request data about both live objects and
those collected by major GC.
3. To tune for minimal GC activity in latency-sensitive applications
like real-time audio processing, the user can request data about
every allocation, including objects collected by major or minor GC.
4. I'm not sure why anybody would want data about objects collected by
minor GC and not objects collected by major GC, but it's also a valid
flags combination.

Original commit message:
[msvc] fix build with neon intrinsics
This compilation error was found by NodeJS when updating V8:
https://github.com/nodejs/node-v8/issues/240
MSVC reports an error with "too many initializer" for type uint32x4_t.
---
Under gcc/clang, this is a typedef to a builtin type.
For MSVC, it is a typedef to this union:
typedef union __n128
{
unsigned __int64 n128_u64[2];
unsigned __int32 n128_u32[4];
...
} __n128;
C++ mandates that only first member of union can be initialized at
declaration. Thus, it can only be initialized with {uint64_t, uint64_t}.
VS people proposed to use designated initializer instead:
var = {.n128_u32={1, 2, 3, 8}}
https://developercommunity.visualstudio.com/t/error-c2078-too-many-initializers-when-using-arm-n/402911
But, you need to use /std:c++20 for this, which is not the case in v8.
---
Thus, the only solution is to implement a hack specifically for MSVC,
where you build two uint64, from four uint32.
---------------------------------------
Once solved, another error is reported:
templated function extract_first_nonzero_index is specialized twice.
This is because, with MSVC, uint32x4_t and uint64x2_t are typedef to the
same __n128 union. The fix is to drop templates, and use explicit
function names instead.
Bug: v8:13312
