Merge lib/Support/WindowsError.cpp into ib/Support/ErrorHandling.cpp.

The OSX ranlib warns on files with no symbols, and lib/Support/WindowsError.cpp
was empty when building on non-windows.

// This file implements a mapping from windows errors to posix ones.
// The standard doesn't define what the equivalence is from system
// errors to generic ones. The one implemented in msvc is too conservative
// for llvm, so we do an extra mapping when constructing an error_code
// from an windows error. This allows the rest of llvm to simple checks
// like "EC == errc::file_exists" and have it work on both posix and
// windows.
