[PATCH] D31295: Add free_on_realloc_zero=true flag for compatibility with allocators which allow a realloc(p, 0) and don't free the pointer.

[Filipe Cabecinhas via llvm-commits]

It is not detected by ASan, no. On `Allocator::Allocate`, we do a
similar `if (size == 0) size = 1;`.

Thank you,
 Filipe
