Rui Ueyama 3e79068e73 Rename sys::Process::GetArgumentVector -> sys::windows::GetCommandLineArguments
GetArgumentVector (or GetCommandLineArguments) is very Windows-specific.
I think it doesn't make much sense to provide that function from sys::Process.

I also made a change so that the function takes a BumpPtrAllocator
instead of a SpecificBumpPtrAllocator. The latter is the class to call
dtors, but since char * is trivially destructible, we should use the
former class.

// The main() functions in typical LLVM tools start with InitLLVM which does
// the following one-time initializations:
//
// 1. Setting up a signal handler so that pretty stack trace is printed out
// if a process crashes.
//
// 2. If running on Windows, obtain command line arguments using a
// multibyte character-aware API and convert arguments into UTF-8
// encoding, so that you can assume that command line arguments are
// always encoded in UTF-8 on any platform.
//
// InitLLVM calls llvm_shutdown() on destruction, which cleans up
// ManagedStatic objects.
