This is a reland of commit 38ef28a058
Fixes:
* Fix comparisons in ASSERT_EQUAL statements on 32-bit architectures.
* Take simulated architectures into account when deciding whether
to use dlopen() for native shared object formats.
* Fix struct/field name collision for GCC.
* Use CPU_TYPE_ANY/CPU_SUBTYPE_ANY for architectures that do not
have more specific cpu_type_t/cpu_subtype_t constants defined.
Original change's description:
> [vm, gen_snapshot] Add app-aot-macho-dylib option for AOT snapshots.
>
> This is the initial framework for creating snapshots as Mach-O dynamic
> libraries. Note that this framework is not 100% feature complete
> compared to generating Mach-O snapshots via assembly. In particular,
> the directly-compiled Mach-O dylib does not yet contain compact
> unwinding information.
>
> Other changes:
>
> * Adds UuidCommand to the native_stack_traces package's Mach-O reader,
> which now appropriately returns the UUID as the build ID for Mach-O
> shared objects.
>
> * Adds Utils::Basename(path) for portably retrieving the basename
> from a path. (Returns nullptr for all arguments where it is not
> currently implemented on Fuchsia or Windows.)
>
> * Adjusts vm/timeline.h to avoid pulling in <mach_o/loader.h> on MacOS,
> as that interferes with uses of the namespaced Mach-O definitions
> in platform/mach_o.h.
>
> * Only attempt to dlopen() a snapshot if ELF is the native format
> for the host platform or the snapshot is not an ELF shared object.
> If dlopen() is used, report the error message if it fails rather
> than attempting to manually load the snapshot as an ELF shared object.
>
> * Fix the magic number stored in DylibAppSnapshot for loaded non-ELF
> dynamic libraries.
>
> * Remove the detection of reverse-endian Mach-O magic numbers in
> DartUtils::SniffForMagicNumber(), since all our Mach-O related code
> assumes host-endian Mach-O files and so there's no point other than
> to give a slightly better error message when failing.
