Richard Smith 4a1cdc1ae5 Add a flag to remap manglings when reading profile data information. ... This can be used to preserve profiling information across codebase changes that have widespread impact on mangled names, but across which most profiling data should still be usable. For example, when switching from libstdc++ to libc++, or from the old libstdc++ ABI to the new ABI, or even from a 32-bit to a 64-bit build. The user can provide a remapping file specifying parts of mangled names that should be treated as equivalent (eg, std::__1 should be treated as equivalent to std::__cxx11), and profile data will be treated as applying to a particular function if its name is equivalent to the name of a function in the profile data under the provided equivalences. See the documentation change for a description of how this is configured. Remapping is supported for both sample-based profiling and instruction profiling. We do not support remapping indirect branch target information, but all other profile data should be remapped appropriately. Support is only added for the new pass manager. If someone wants to also add support for this for the old pass manager, doing so should be straightforward. This is the LLVM side of Clang r344199.
