  Validate anonymous struct names with namespace
  
  Consider GLSL:
      struct { vec4 e; } g;
      struct sbbf { vec4 f; };
  
  The struct name validation would fail if user chosen struct name would
  clash with a symbol name that ANGLE internally gave to an anonymous
  struct.
  
  Fix by importing Name abstraction from MSL backend. A symbol name is
  a pair (namespace, string).
  
  Move  operator<<(std::ostream &os, const ImmutableString &str)
  to sh namespace because that is more natural for operator overloading
  name resolution. MSVC works with this.
