Reapply [LLD] [COFF] Implement a GNU/ELF like -wrap option Add a simple forwarding option in the MinGW frontend, and implement the private -wrap option in the COFF linker. The feature in lld-link isn't gated by the -lldmingw option, but the option is left as a private, undocumented option primarily used by the MinGW driver. The implementation is significantly based on the support for --wrap in the ELF linker, but many small nuance details are different between the ELF and COFF linkers, ending up with more than a few implementation differences. This fixes https://bugs.llvm.org/show_bug.cgi?id=47384. Differential Revision: https://reviews.llvm.org/D89004 Reapplied with the bitfield member canInline fixed so it doesn't break builds targeting windows.
