Add newly released mold version 2.32.0 from upstream
https://github.com/rui314/mold
New features
- mold supports a feature called Identical Code Folding, or ICF. As the
name suggests, ICF finds identical functions and merges them to reduce
the size of an output file. This is especially effective for
template-heavy C++ programs since templates tend to be instantiated to
the same machine code for different types. For example,
std::vector<int> is likely to be instantiated to the same code as
std::vector<unsigned>. We've made an improvement to our ICF algorithm
so that the --icf feature is ~50% faster than the previous version.

- The -z rodynamic option is now supported for compatibility with LLVM
lld. With the option, mold places the .dynamic section into a
read-only segment. (9a233df)
Bug fixes and compatibility improvements
- Previously, mold behaved differently compared to other linkers if both
-z defs and --undefined=ignore-in-object-files were given (#1270).
Now, they override each other so that the mold's behavior is
compatible with others. (8cd85aa)
- Previously, --dependency-file mistakenly recorded response files as
dependencies (#1258). This bug has been fixed. (4281f45)
- There was a bug that mold corrupted debug info section contents when
the --relocatable option was given (#1265). This issue has been fixed.

- [PPC64] The R_PPC64_TPREL16_LO_DS relocation type is supported.

- [ARM64, PPC64, LoongArch] mold 2.31.0 or earlier may have failed with
an assertion failure when creating a large output file (#1224). This
issue has been resolved. (c7c8583)
