* changelog

* update grammar mutator

* lto llvm 12+

* docs(custom_mutators): fix missing ':' (#1953)

* Fix broken LTO mode and response file support (#1948)

* Strip `-Wl,-no-undefined` during compilation (#1952)

Make the compiler wrapper stripping `-Wl,-no-undefined` in addition to `-Wl,--no-undefined`.
Both versions of the flag are accepted by clang and, therefore, used by building systems in the wild (e.g., samba will not build without this fix).

* Remove dead code in write_to_testcase (#1955)

The custom_mutators_count check in if case is duplicate with if condition.
The else case is custom_mutators_count == 0, neither custom_mutator_list iteration nor sent check needed.
