lld-link: Fix subsystem inference for non-console apps on 32-bit, and fix entry point inference on 32-bit with /nodefaultlib LinkerDriver::inferSubsystem() used to do Symtab->findUnderscore("WinMain"), but WinMain is stdcall in 32-bit and is hence is called _WinMain@16. Instead, Symtab->findMangle(mangle("WinMain")) needs to be called. But since LinkerDriver::inferSubsystem() and LinkerDriver::findDefaultEntry() both need to call this, introduce a common helper function for this and call it from both places. (Also call it for "main" for consistency, even though findUnderscore() is enough for main since that's __cdecl on 32-bit). This also exposed a bug for /nodefaultlib entrypoint inference: The code here called findMangle(Sym) instead of findMangle(mangle(Sym)), again doing the wrong thing on 32-bit. Fix that too. While here, make Driver::mangle() a static free function. https://reviews.llvm.org/D50184 llvm-svn: 338877

[COFF] Implement /safeseh:no and check @feat.00 flags by default Summary: Fixes PR41828. Before this, LLD always emitted SafeSEH chunks and defined __safe_se_handler_table & size. Now, /safeseh:no leaves those undefined. Additionally, we were checking for the safeseh @feat.00 flag in two places: once to emit errors, and once during safeseh table construction. The error was set up to be off by default, but safeseh is supposed to be on by default. I combined the two checks, so now LLD emits an error if an input object lacks @feat.00 and safeseh is enabled. This caused the majority of 32-bit LLD tests to fail, since many test input object files lack @feat.00 symbols. I explicitly added -safeseh:no to those tests to preserve behavior. Finally, LLD no longer sets IMAGE_DLL_CHARACTERISTICS_NO_SEH if any input file wasn't compiled for safeseh.
