Since C++14 has been released for about nine years and most standard libraries have implemented sized deallocation functions, it's time to make this feature default again. This is another try of https://reviews.llvm.org/D112921. The original commit cf5a8b4 was reverted by 2e5035a due to some failures (see #83774). Fixes #60061
