Recommit: Stop intercepting some malloc-related functions on FreeBSD and macOS Summary: In https://bugs.freebsd.org/215125 I was notified that some configure scripts attempt to test for the Linux-specific `mallinfo` and `mallopt` functions by compiling and linking small programs which references the functions, and observing whether that results in errors. FreeBSD and macOS do not have the `mallinfo` and `mallopt` functions, so normally these tests would fail, but when sanitizers are enabled, they incorrectly succeed, because the sanitizers define interceptors for these functions. This also applies to some other malloc-related functions, such as `memalign`, `pvalloc` and `cfree`. Fix this by not intercepting `mallinfo`, `mallopt`, `memalign`, `pvalloc` and `cfree` for FreeBSD and macOS, in all sanitizers. Also delete the non-functional `cfree` wrapper for Windows, to fix the test cases on that platform. Reviewers: emaste, kcc, rnk Subscribers: timurrrr, eugenis, hans, joerg, llvm-commits, kubamracek Differential Revision: https://reviews.llvm.org/D27654 This prevents autoconf scripts from incorrectly detecting that functions like mallinfo, mallopt, memalign, pvalloc and cfree are supported.
