Parser: Implement extension GL_AMD_gpu_shader_half_float.
- Add built-in types: float16_t, f16vec, f16mat. - Add support of half float constant: hf, HF. - Extend built-in floating-point operators: +, -, *, /, ++, --, +=, -=, *=, /=, ==, !=, >=, <=, >, <. - Add support of type conversions: float16_t -> XXX, XXX -> float16_t. - Add new built-in functions.
