[clang][CodeGen] Emit llvm.tbaa.errno metadata during module creation
Let Clang emit `llvm.tbaa.errno` metadata in order to let LLVM carry out optimizations around errno-writing libcalls to, as long as it is proved the involved memory location does not alias `errno`. Previous discussion: https://discourse.llvm.org/t/rfc-modelling-errno-memory-effects/82972.
