URL: https://github.com/llvm/llvm-project/commit/feb1fb5f0473eb949b35fb25e15c4d32465cd6d7 DIFF: https://github.com/llvm/llvm-project/commit/feb1fb5f0473eb949b35fb25e15c4d32465cd6d7.diff LOG: Make the `-disable-free` flag more full featured (#136213) This lets us pass `-no-disable-free` to re-enable freeing memory for example. This is especially helpful for library users of Clang where it is important to not slowly leak memory.
