[ELF,LTO] Test calloc defined in a lazy bitcode file for (malloc+memset => calloc) libcall optimization Similar to https://reviews.llvm.org/D50017: malloc+memset references can be combined to a calloc reference, which is not explicit in the referencer's IR symbol table. If calloc is defined in a lazy bitcode file, we should extract the archive member to satisfy possible references from LTO generated object files; otherwise (current status, which will be fixed by #72673), `calloc` as a LazyObject symbol will be resolved by compileBitcodeFiles generated Undefined, leading to an incorrectly-extracted Defined symbol without section, which will lower to an SHN_ABS symbol at address 0.
