LOG: [LLD] [docs] Add more release notes for COFF and MinGW (#81977)

Add review references to all items already mentioned.

Move some items to the right section (from the MinGW section to COFF, as
the implementation is in the COFF linker side, and may be relevant for
non-MinGW cases as well).

Added:

 * Added support for ``--time-trace`` and associated ``--time-trace-granularity``.
   This generates a .json profile trace of the linker execution.
+  (`#68236 <https://github.com/llvm/llvm-project/pull/68236>`_)
+
+* The ``-dependentloadflag`` option was implemented.
+  (`#71537 <https://github.com/llvm/llvm-project/pull/71537>`_)
 
 * LLD now prefers library paths specified with ``-libpath:`` over the implicitly
   detected toolchain paths.
+  (`#78039 <https://github.com/llvm/llvm-project/pull/78039>`_)
+
+* Added new options ``-lldemit:llvm`` and ``-lldemit:asm`` for getting
+  the output of LTO compilation as LLVM bitcode or assembly.
+  (`#66964 <https://github.com/llvm/llvm-project/pull/66964>`_)
+  (`#67079 <https://github.com/llvm/llvm-project/pull/67079>`_)
+
+* Added a new option ``-build-id`` for generating a ``.buildid`` section
+  when not generating a PDB. A new symbol ``__buildid`` is generated by
+  the linker, allowing code to reference the build ID of the binary.
+  (`#71433 <https://github.com/llvm/llvm-project/pull/71433>`_)
+  (`#74652 <https://github.com/llvm/llvm-project/pull/74652>`_)
+
+* A new, LLD specific option, ``-lld-allow-duplicate-weak``, was added
+  for allowing duplicate weak symbols.
+  (`#68077 <https://github.com/llvm/llvm-project/pull/68077>`_)
+
+* More correctly handle LTO of files that define ``__imp_`` prefixed dllimport
+  redirections.
+  (`#70777 <https://github.com/llvm/llvm-project/pull/70777>`_)
+  (`#71376 <https://github.com/llvm/llvm-project/pull/71376>`_)
+  (`#72989 <https://github.com/llvm/llvm-project/pull/72989>`_)
+
+* Linking undefined references to weak symbols with LTO now works.
+  (`#70430 <https://github.com/llvm/llvm-project/pull/70430>`_)
 
 * Use the ``SOURCE_DATE_EPOCH`` environment variable for the PE header and
   debug directory timestamps, if neither the ``/Brepro`` nor ``/timestamp:``
   options have been specified. This makes the linker output reproducible by
   setting this environment variable.
+  (`#81326 <https://github.com/llvm/llvm-project/pull/81326>`_)
+
+* Lots of incremental work towards supporting linking ARM64EC binaries.
 
 MinGW Improvements

 * Added support for many LTO and ThinLTO options (most LTO options supported
   by the ELF driver, that are implemented by the COFF backend as well,

 * LLD no longer tries to autodetect and use library paths from MSVC/WinSDK
   installations when run in MinGW mode; that mode of operation shouldn't
   ever be needed in MinGW mode, and could be a source of unexpected
   behaviours.

   info and symbol tables while emitting a PDB debug info file.
