1cefbacd - [libc++] Replace the of use custom sections for detecting overriden functions (#175896)

[libc++] Replace the of use custom sections for detecting overriden functions (#175896) This is a follow up to #133876 and an alternative to #120805 which doesn't rely on aliases and works across both ELF and Mach-O. This mechanism is preferable in baremetal environments since it doesn't require special handling of the custom sections.
