Martin Storsjo ddb094ad36 [COFF] Fix exporting of functions starting with underscores, etc
This fixes exporting functions in the following cases:
- functions starting with an underscore in def files
- functions starting with an underscore, via dllexport attributes, for mingw
- fastcall and vectorcall functions when declared undecorated in def files
- vectorcall functions when declared decorated in def files
- stdcall functions when declared decorated in def files for mingw

This still exports the stdcall functions with the wrong name
in the normal msvc/link.exe mode, if declared with decoration in
the def file though (this is not a regression though). Exporting
functions via def files including decoration is not something I
believe is routinely done though, but is tested to try to match
link.exe's behaviour as far as easily possible.

Martin Storsjo 31fe4cd25d [MinGW] Support dllexport on i386
In MinGW configurations (GCC, or clang with a *-windows-gnu target),
the -export directives in the object file contains the undecorated
symbol name, while it is decorated in MSVC configurations. (On the
command line, link.exe takes an undecorated symbol name for the
-export argument though.)
