  Statically allocate built-in function symbols
  
  A script gen_builtin_symbols.py now generates code for initializing
  built-in function symbols. The TFunction objects are initialized at
  C++ compile time.
  
  The source file used for the functions is in a format that's similar
  to how functions are given out in the GLSL spec, so it is easy to
  maintain.
  
  The function symbols are still inserted to the symbol table levels
  same as before. Getting rid of inserting the symbols at runtime is
  intended to be done as follow-up.
  
  This speeds up angle_unittests on Linux in release mode by a bit less
  than half, and in debug mode by more than half.
