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.

32c169dbdf Front-end: Warn for likely missed change in default precisions. 
This is part of the change to have desktop shaders respect precision
qualifiers on Vulkan, but since the defaults are all highp, and that's
different from ES fragment shaders, detect likely cases and warn about
them (but being careful to not be too noisy if it's unlikely to be a
problem).

4d535640e4 Front-End: Non-ES trigger for processing precision qualifiers. 
Initially non-functional: Have an independent test for whether to obey
precision qualifiers other than whether the profile is es.

b10feabc95 Front-end: Non-functional: Move return-value handling from .y to .cpp. 
This is to make the real change needed in the next commit easier.

d94c003fb7 Front-end: Complete GL_ARB_compute_shader implementation. 
Core compute shaders were working, but the extension wasn't implemented.

17f0786418 Parser: Precise: Recognize 'precise', tag types, and do related semantic checking. 
This partly overlaps pull request #222, we have divided the work on this one.

758bb5520d Bison: Non-functional: Move to revision 3.0.4. 
This hopefully prevents obsucuring actual changes in a future commit.

Also, adds a script to update the grammar.
