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.

8d72f1a2c4 Full stack: distinguish between a scalar and a vector of size 1. 
There have been GLSL extensions considering this, and HLSL does it.
This is a fully backward compatible change that allows this distinction.

0840838d17 Support specialization composite constants 
Fix issue #163, support creation and reference of composite type
specialization constants.

e.g.:
```
layout(constant_id = 200) const float myfloat = 1.25;
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).

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.

65c78a0b62 Array of array: Implement the core functionality: types, constructors, operations. 
There will be subsequent commits to refine semantics, esp. version-specific semantics,
as well as I/O functionality and restrictions.

Note: I'm getting white-space differences in the preprocessor test results,
which I'm not checking in.  I think they need to be tagged as binary or something.

150b7acd9a Restore r26192, r26240, r26241: All three about implicit-array sizing design and implementation. *Minus* test results. 
r26192: Link-time sizing of implicitly-sized arrays and handling of anonymous blocks containing implicitly-sized members.  Also changed "__anon" to "anon@" and encapsulated it.

r26240: Solidify the sharing of struct and array information between nodes and variables: A single copy now allows for simultaneously setting array size for all effected nodes and symbols of a given type. This allowed removal of ioArrayNodeResizeList and makes nodes of implicitly sized arrays know the final size.

Also
 - uniformly handle EvqConstReadOnly as an input argument in a function, with

 - provide a makeTemporary() in TQualifier, for erasing original qualification when making a temp
 - provide a makeInternalVariable() call to make a shader variable not seen in the shader source
