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.

6373574b13 Front-end: Fix: Cubemap arrays only use 3-component coord when accessed as an image. 
4 components are needed when used a texture, but not an image, which multiplies
layers and faces into the same coordinate.  This fixes it from using 4 everywhere,
to only using 4 for textures and 3 for images.

fa668dad99 SPV: Reduce spurious type generation by removing intermediate types in the middle of access chains. 
This generally simplifies access chain generation, with far fewer  type conversions.
It is particularly important to future SPIR-V changes where there is less aggregate
type uniqueness due to carrying different layout information with the type.

fc51d284aa Backward incompatible: Turn on PureOperatorBuiltins: use only enum-based built-in functions in the AST. 
If this breaks your AST consumer, best is to modify it to test
against the enum values instead of doing string comparisons on
built-in function names.  This is the reason the change was made.

If you need the old behavior, you should be able to get it back by changing
PureOperatorBuiltins to be false instead of true.  This path will work for
a while, but is marked deprecated.

Also, the old behavior is tagged as release 2.4.

28f9b1c28d SPIR-V: Return undefined values from implicit returns instead of dummy 
Previously if a non-void function implictly returned, a dummy variable
was created as return value. Now instead it returns the result of the
OpUndef instruction. This better conveys the presence of undefined
behavior to SPIR-V consuming tools (and humans).

It also saves one ID per occurrence...

65c78a0b62 Array of array: Implement the core functionality: types, constructors, operations. 
There will be subsequent commits to refine semantics, esp. version-specific semantics,

which I'm not checking in.  I think they need to be tagged as binary or something.

9c1280b225 Use extension framework to enable #include directive. 
This patch introduces a new extension, GL_GOOGLE_include_directive,
to enable support #include directives. It depends on the extension
GL_GOOGLE_cpp_style_line_directive.

7be4b8282d Add #include processing to glslang (though turned off by default). 
When an include directive is recognized by the preprocessor, it
executes a callback on the filepath argument to obtain the file
contents.  That way the compilation client can deal with the file
system, include paths, etc.

Currently only accepts quoted filepaths -- no angle brackets yet.

5011fbebc3 Extend the syntax of #line and __FILE__ to support filename strings. 
According to the GLSL spec, the second parameter to #line should be
an integer source string number and __FILE__ will be substituted
with the integer source string number currently processed. This
patch extends the syntax of #line and __FILE__. Now #line accepts
as the second parameter a filename string quoted by double quotation
marks. And if such a #line is set, __FILE__ will be substituted with
the currently set filename string. The implementation is done via
introducing a new extension GL_GOOGLE_cpp_style_line_directive using
the extension framework.

The purpose is to support cpp-style #line directives, which is
required by #include.

c777fc2c4c Scanning: 1) rationalize end-of-input everywhere, 2) prevent infinite loop at end-of-input, 3) use positive chars. 
Fixes issue #25. (char 255 aliased to -1 and missing tests for end of input).

1) All layers of input scanning now share a single EndOfInput value.
This avoids translation of it across layers of encapsulation.

2) Some places looking for end of line were not stopping on EndOfInput.

3) Use of "char" for the input made char values > 127 be negative numbers.
This allowed for aliasing of 255 to -1, etc.  This is fixed by using
unsigned char.

3e6a33cedf spv::Builder::Loop constructor inits all members. 
After construction, the Loop is effectively const.

This perturbs the IDs in SPIR-V tests because the body block

only when the body is first referenced.

c22f37cfb4 Generate correctly structured do-while loops. 
The loop test is always emitted before the loop body.

For do-while loops, use a phi node to track whether we're
on the first loop iteration, and only check the loop test
on the second and subsequent iterations.

For do-while loops, the loop test branch no longer occurs
at the top of the loop, so it must get its own selection
merge instruction.

A block can't be the target of more than one merge instruction.
So when the loop test executes after the body (as in do-while in GLSL)
we need to introduce a dummy block to be the target of the selection
merge just before the loop test conditional branch.

The other arm of the branch exits the loop and hence is the
"break block" exception in the structured control flow rules.

5cbc990a0a Fix line number handling in line directive callback. 
The line argument passed into the lineCallback function is the
literal value of the first argument of the #line directive.
lastLine in DoPreprocessing() should be updated taking into
consideration the different definitions for #line between specs.

Add a test to reveal the bug.
