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.

5e56423046 Front-ends: Remove now defunct afterEOF and related, use scanner's instead.
Code using atEndOfFile was dead, instead do something useful with
the scanners atEndOfInput().  This allows a better error message
for early termination of cascading errors.

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).

54571c2519 Vulkan: Have desktop shaders respect precision qualifiers.
Sets highp defaults for the appropriate types, for all stages,
and turns on precision qualifiers for non-ES shaders.  Required
fixing some qualifier orders for desktop built-in declarations
for pre-420 shaders.

370234888d Front-end: Add a function selector under implicit type conversion.
Use the new function selector for #version 400 and above,
parameterized for the GLSL #version 400 selection rules.

This can be used for both GLSL and HLSL, and other languages
as well.

f6640761c4 Front-end: Implement 2nd task of issue #400; precision of result and operation.
From the ES spec + Bugzilla 15931 and GL_KHR_vulkan_glsl:
- Update precision qualifiers for all built-in function prototypes.
- Implement the new algorithm used to distinguish built-in function
  operation precisions from result precisions.
Also add tracking of separate result and operation precisions, and
use that in generating SPIR-V.
(SPIR-V cares about precision of operation, while the front-end
cares about precision of result, for propagation.)

  (SPV_AMD_shader_explicit_vertex_parameter).

a86836ede2 Front-end: Fix known crashes by early exit on error (issue #29, issue #34, issue #35).
Added -C option to request cascading errors.  By default, will exit early,
to avoid all error-recovery-based crashes.

This works by simulating end-of-file in input on first error, so no
need for exception handling, or stack unwinding, or any complex error
checking/handling to get out of the stack.

d82c906378 Vulkan: Finish semantics for what creates spec-const-semantics.
Note: This required adding a new test mode to see the AST for vulkan tests.
This also required reworking some deeper parts of type creation, regarding
when storage qualification and constness is deduced bottom-up or dictated
top-down.
