Original commit description: [LLD] Remove global state in lld/COFF This patch removes globals from the lldCOFF library, by moving globals into a context class (COFFLinkingContext) and passing it around wherever it's needed. See https://lists.llvm.org/pipermail/llvm-dev/2021-June/151184.html for context about removing globals from LLD. I also haven't moved the `driver` or `config` variables yet. Differential Revision: https://reviews.llvm.org/D109634 This reverts commita2fd05ada9
