Load dyld manually with 'main bin spec' userland corefiles

binary and a 'main bin spec' LC_NOTE detailing the UUID and
load address, ProcessMachCore will do a (potentially slow)
lookup to try to find the binary and/or dSYM. For kernel and
userland corefile using 'main bin spec', we would follow the
normal schemes of locating them. DynamicLoaderDarwinKernel would
use the same (possibly expensive) calls to find the correct
binary. dyld by default would use the in-core-file binary image,
and so if the corefile didn't include the entire address space,
the LINKEDIT for dyld could be missing. This means we can't find
the dyld4::dyld_all_image_infos struct, which tells us where the
other binaries are loaded in memory.
Treat userland 'bin main spec' like we do standalone firmewares;
try the expensive checks to find the best dyld we can, before
falling back to using a memory module out of the corefile.
Also add a little TODO for myself in this load_standalone_binary
function that we should handle the case of a binary in the shared

[llvm-profgen] Decoding pseudo probe for profiled function only.
Complete pseudo probes decoding can result in large memory usage. In practice only a small porting of the decoded probes are used in profile generation. I'm changing the full decoding mode to be decoding for profiled functions only, though we still do a full scan of the .pseudoprobe section due to a missing table-of-content but we don't have to build the in-memory data structure for functions not sampled.
To build the in-memory data structure for profiled functions only, I'm rewriting the previous non-recursive probe decoding logic to be recursive. This is easy to read and maintain.
I also have to change the previous representation of unsymbolized context from probe-based stack to address-based stack since the profiled functions are unknown yet by the time of virtual unwinding. The address-based stack will be converted to probe-based stack after virtual unwinding and on-demand probe decoding.
I'm seeing 20GB memory is saved for one of our internal large service.

[libc++] Add a lightweight overridable assertion handler
This patch adds a lightweight assertion handler mechanism that can be
overriden at link-time in a fashion similar to `operator new`.
This is a third take on https://llvm.org/D121123 (which allowed customizing
the assertion handler at compile-time), and https://llvm.org/D119969
(which allowed customizing the assertion handler at runtime only).
This approach is, I think, the best of all three explored approaches.
Indeed, replacing the assertion handler in user code is ergonomic,
yet we retain the ability to provide a custom assertion handler when
deploying to older platforms that don't have a default handler in
the dylib.
As-is, this patch provides a pretty good amount of backwards compatibility
with the previous debug mode:
- Code that used to set _LIBCPP_DEBUG=0 in order to get basic assertions
in their code will still get basic assertions out of the box, but
those assertions will be using the new assertion handler support.
- Code that was previously compiled with references to __libcpp_debug_function
and friends will work out-of-the-box, no changes required. This is
because we provide the same symbols in the dylib as we used to.
- Code that used to set a custom __libcpp_debug_function will stop
compiling, because we don't provide that declaration anymore. Users
will have to migrate to the new way of setting a custom assertion
handler, which is extremely easy. I suspect that pool of users is
very limited, so breaking them at compile-time is probably acceptable.
The main downside of this approach is that code being compiled with
assertions enabled but deploying to an older platform where the assertion
handler didn't exist yet will fail to compile. However users can easily
fix the problem by providing a custom assertion handler and defining
the _LIBCPP_AVAILABILITY_CUSTOM_ASSERTION_HANDLER_PROVIDED macro to
let the library know about the custom handler. In a way, this is
actually a feature because it avoids a load-time error that one would
otherwise get when trying to run the code on the older target.
