Fangrui Song d496abbe2a [lld-link] Replace LazyObjFile with lazy ObjFile/BitcodeFile 
Similar to ELF 3a5fb57393.

* 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 (5200+ bytes smaller on x86-64)
* make eager parsing feasible (for parallel section/symbol table initialization)
