Rui Ueyama 9420dee328 COFF: Fix export symbol names for x86.
I don't fully understand the rationale behind the name mangling
scheme used for the DLL export table and the import library.
Why only leading "_" is dropped for the import library while
both "_" and "@" are dropped from DLL symbol table? But this seems
to be what MSVC linker does.

Rui Ueyama 8765fbae15 COFF: Fix mangled dllexported names.
If a symbol is exported as /export:foo, and foo is resolved as a
mangled name (_foo@<number> or ?foo@@Y...), that mangled name should
be written to the export table. Previously, we wrote the original
name to the export table.

Rui Ueyama 270960f5cd COFF: Find C++ mangled name for symbols starting with underscore.
Symbol foo is mangled as _foo in C and ?foo@@... in C++ on x86.
findMangle has to remove prefix underscore before mangle a given name
as a C++ symbol.

Rui Ueyama bbdec4fc82 COFF: Fix dllexported symbol names on x86.
Symbol names are usually mangled by appending "_" prefix on x86.
But the mangled name is not used in DLL export table. The export
table contains unmangled names.
