61d9fb9048 Semantics: 'invocations' defaults to 1, not 0.
'invocations' was using 0 as the "shader never set" flag and as the
default. Formalize this and explicit set to 1 and link time.

494a02a2b0 Semantics: Geometry stage can support max_vertices = 0.
To do this, more generally use a named -1 as a not set value.

dff18a2be0 glslang: Formally track all built-in variables, right from the beginning, to enable avoiding all textual compares at any subsequent stage in the stack. (To be used in future check ins.)

8b37b04ecc glslang AST output: include global vs. temp (local) in the printed output. This only effects test results, but a future check-in is going to fix some globals.

cf0206c341 Restore r26245 and all tests and test results since 4/1:
r26245: Remove "not yet complete" warning for versions 130 and 140, after tidying up a bit and adding tests.  Token pasting is the only known missing feature, and gives its own message now on use.

f2d042a1fe Non-functional, infrastructure: Be more explicit about "implicit array sizes", improving the infrastructure for handling them. Also fix some output that was too big for its buffer.
There is more upcoming functionality for link-time sizing of implicitly-sized arrays that will use this.

5053a39578 Fix slight inconsistencies in which qualifiers are inherited into block members:
- don't inherit 'binding'
 - always set the member storage qualifier, not just when the shader explicitly set it
 - don't include in/out members as objects that are resized by geometry/primitive layout specifiers
As a side effect, this makes built-in redeclarations (like gl_ClipDistance) require in/out.

7cbfdf4394 Minor infrastructure changes, to simplify an upcoming check in:
- print out block member types when printing a block (makes all test results change)
 - const versions of all intermediate.h type-identification methods
 - layoutSlotLocation -> layoutLocation

f3e2a89452 Tessellation: Implicit array sizing and consistency checking of control-shader output arrays based on layout(vertices=...).

623833fabc Tessellation partial implementation (not ready for use yet), including:
- the built-in constants
 - built-in variable declarations, some dependent on gl_MaxPatchVertices
 - layout qualifier for vertices (shared with geometry shader max_vertices)
 - layout qualifiers for vertex spacing, vertex order, point mode, and primitive type
 - link semantics for layout qualifiers

Still TBD:
 - patch qualifier and arrayed input handling
 - sizing of gl_out[]
 - additional semantic checking
 - supporting the extension on version 150

c719481d43 Flesh out 4.x block redeclaration semantics:
- hide non-redeclared anonymous members
 - array size limit checking
 - illegal member qualifiers
 - additional members

5134b9cf57 Track what ins/outs/uniforms are used, so that errors like "declare after use" or "can't use both XXX and YYY" can be issued. So far, used this for invariant, gl_FragColor et. al., and gl_FragCoord use before redeclaration.
Also made all tests in testlist include linker tests.

e7c59c187c Add all built-in variables for all versions/profiles/stages of GLSL. Also, made more readable; declarations are cut and paste from the specs, with quotes around them. This does not include built-in constants yet (other than MaxClipDistances), just the non-constants.

fb57e7cc5e Add ES 3.0 fragment output link-time test for outputs having or not having location qualifiers.
Also split linker validation into its own file, removed dead "QualifierAlive" files, printed errors for parsing problems with built-in symbols,  updated the Windows binary, and added some tests.
