  Always add most extension symbols to symbol table
  
  An error will be generated either way if the extension symbols are
  used incorrectly since each use of an extension function or variable
  checks whether the extension is enabled.
  
  We now also track extension in unmangled built-in names, so that
  redefining built-ins of extensions that are not enabled can be
  supported.
  
  This includes refactoring the shader extension tests to share a common
  helper class ShaderExtensionTest.
