[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.
