Original commit message:

    [simd] Disable SVE implementation of array search for GCC

    GCC requires SVE enabled for the entire translation unit and does
    not expose raw __builtin_sve_* builtins on a per-function basis.
    Fallback to Neon if it's not built by Clang.

ICU_UTIL_DATA_SHARED had been removed since
https://crrev.com/c/1513615, but Node.js still defined
it and relied on the removed path on Windows, so the ICU
initialization in mksnapshot had been silently failing
since then. https://crrev.com/c/7679153 made the failure
visible so the build started breaking on Windows. Fix it
by always using ICU_UTIL_DATA_STATIC since we already compile
the ICU data statically in.

V8 bumped its wire-format version from 0x0f to 0x10. Update the
expected hex in test-v8-serdes, and derive the v8 header bytes
dynamically in test-runner-v8-deserializer so it tracks future
bumps automatically.

V8 no longer supports JSON.parse on worker isolates while the shared
string table is enabled. Since --harmony-struct enables that table and
Node workers parse process.config during bootstrap,
use direct MessageChannel instead of a worker.

Original commit message:

    [platform][posix] Fallback to conservative stack limit on musl

    For most libcs, pthread_getattr_np() returns the the stack reserved
    limit on the main thread, but musl only returns the current high-water
    mark at the time of the call. There's no macro to detect musl, so just
    fallback to the conservative stack limit in cases where the libc is
    not one that is known to work.

Original commit message:

    AIX: implement Stack::ObtainCurrentThreadStackReservedLimit

    Port 5a54f45b671bdf47e083ffbad547713d8bacb28f

    AIX lacks `pthread_getattr_np()` so we implement the function using
    pthread_getthrds_np() with PTHRDSINFO_QUERY_ALL, consistent with
    ObtainCurrentThreadStackStart(). The `__pi_stackaddr` field maps to the
    lowest stack address, equivalent to the base returned by
    pthread_attr_getstack() on other POSIX platforms.

    IT: 145
