RFR: JDK-8166748 Clean out Windows IA64 support

[Bob Vandette]

The register code area support was only added for Windows IA64.

  // Give OS a chance to register generated code area.
  // This is used on Windows 64 bit platforms to register
  // Structured Exception Handlers for our generated code.
  os::register_code_area((char*)low_bound(), (char*)high_bound());

The dependency checker support was for all IA64 platforms.
