4c9876b34c Add names for composite constants in SPIR-V
Consider the following code:

    layout(constant_id=0) const int Y = 1;
    layout(constant_id=1) const int Z = 2;
    layout(constant_id=3) const int X = Y + Z;

Previously, it would produce SPIR-V decorations like this:

    Decorate 21(Y) SpecId 1
    Decorate 22 SpecId 3
    Decorate 33(Z) SpecId 0

This seems inaccurate, since the spec constant `X` that is dependent on
the two others did not get a name in the SPIR-V decorations. This behavior
may potentially negatively affect shader introspection capabilities.

This change alters the behavior to always add a name, which results in the code
above producing the following decorations:

    Decorate 21(Y) SpecId 1
    Decorate 22(X) SpecId 3
    Decorate 33(Z) SpecId 0

ac3707921e Revert the commits that change OpArrayLength type and bumped the version number.
Now, version 5.* is all connected to making the uint type, which doesn't quite work.
Generator versions 4 and 6 do not do this.

c9e3c3c941 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.
