LLD: Introduce a GNU LD style driver for COFF When building COFF programs many targets such as mingw prefer to have a gnu ld frontend.

[LLD] [COFF] Add options for disabling auto import and runtime pseudo relocs Allow disabling either the full auto import feature, or just forbidding the cases that require runtime fixups. As long as all auto imported variables are referenced from separate .refptr$<name> sections, we can alias them on top of the IAT entries and don't actually need any runtime fixups via pseudo relocations. LLVM generates references to variables in .refptr stubs, if it isn't known that the variable for sure is defined in the same object module. Runtime pseudo relocs are needed if the addresses of auto imported variables are used in constant initializers though. Fixing up runtime pseudo relocations requires the use of VirtualProtect (which is disallowed in WinStore/UWP apps) or VirtualProtectFromApp. To allow any risk of ambiguity, allow rejecting cases that would require this at the linker stage. This adds support for the --disable-runtime-pseudo-reloc and --disable-auto-import options in the MinGW driver (matching GNU ld.bfd) with corresponding lld private options in the COFF driver.

As mingw setups don't generally use SEH on 32 bit x86 at all, it should be fine to set that flag bit though - hook up the existing GNU ld flag for controlling that.

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.
