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.

af459216a1 Correct precision qualification on built-in functions. 
This is a replacement commit for pull request #238.

This is a design change, followed by implementation change that
A) fixes the changes caused by the design change, and
B) fixes some cases that were originally incorrect.

The design change is to not give built-in functions default precision qualification.
This is to allow the rule that the precision of some built-in functions adopt their
precision qualification from the calling arguments.  This is A above.

A consequence of this design change is that all built-ins that are supposed to have
an explicit precision qualifier must now be declared that way.  So, a lot more
built-in declarations now have precision qualifiers, just to keep things the same.
This is B above.

8ff43de891 Implement the extension GL_ARB_gpu_shader_int64 
- Add new keyword int64_t/uint64_t/i64vec/u64vec.
- Support 64-bit integer literals (dec/hex/oct).
- Support built-in operators for 64-bit integer type.
- Add implicit and explicit type conversion for 64-bit integer type.
- Add new built-in functions defined in this extension.

Fix issue #163, support creation and reference of composite type
specialization constants.

layout(constant_id = 201) const int myint = 14;
struct structtype {
  float f;
  int i;
};
const structtype outer_struct_var = {myfloat, myint};
void main(){}

Rname two function names to match their functionalities.
1) Rename `GlslangToSpvTraverser::createSpvSpecConstant()` to
`createSpvConstant()`;
2) Rename `GlslangToSpvTraverser::createSpvConstant()` to
`createSpvConstantFromConstUnionArray()`

Add function `GlslangToSpvTraverser::createSpvConstantFromSubTree()` to
handle constant creation from sub trees (e.g.: specialization constants).

7cc0e2896e Front-end infrastructure: Encapsulate semantic-level questions/actions about const/temp. 
Much about const or temp is mechanical, about actual declaration,
while much is semantic, about something higher level.  This commit
checks every use everywhere, and for the high-level ones, substitutes
an encapsulated version instead.

b3dc3acd59 Refactor TParseContext into 3 level inheritance. 
Adds parseVersions.h as the base TParseVersions for versioning,
and splits the remainder between TParseContextBase (sharable across parsers)
and TParseContext (now the GLSL-specific part).

989df85dcd Array-sizing bug fix: multiple array initializers of different size in the same declaration. 
Handles the case of
    float[] x = float[] (1.0, 2.0, 3.0),
            y = float[] (1.0, 2.0, 3.0, 4.0);
where a shallow copy of the type arrayness from the left-most float[]
was getting used twice.
