[lld] Support for PECOFF in gnu ld mode

[Rui Ueyama]

Hi Martell,

The first and the second patches look good. They just add __image_base__ as
an alias for __ImageBase (I don't know why mingw uses different symbols
than regular Windows symbols, though).

The rest is to support COFF files with GNU command line driver. I don't
know if we want to support that. Do you think even if we have a complete
link.exe-compatible linker, we still want to use GNU ld-compatible COFF
linker on Windows?
