48a6f2f8 - [Object][Archive] Recompute headers and symbol map when switching from COFF to GNU64 (#160606)

[Object][Archive] Recompute headers and symbol map when switching from COFF to GNU64 (#160606) COFF format has no 64-bit version, so we use GNU64 instead. Since this changes the headers, we need to recalculate everything. Fixes #160112.
