Similar to ELF 3a5fb57393c3bc77be9e7afc2ec9d4ec3c9bbf70 <https://reviews.llvm.org/rG3a5fb57393c3bc77be9e7afc2ec9d4ec3c9bbf70>.

- previously when a LazyObjFile was extracted, a new ObjFile/BitcodeFile was created; now the file is reused, just with `lazy` cleared
- avoid the confusing transfer of `symbols` from LazyObjFile to the new file
- simpler code, smaller executable (6500+ bytes smaller on x86-64)
- make eager parsing feasible (for parallel section/symbol table initialization)
