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.

Add full support for uniforms with initializers, including intra-stage link validation of aggregate constant initializers.
...
This included
- encapsulating aggregate constants
- removal of constant-aggregate comparison algorithms, instead using a flattened and direct std::vector comparison
- adding structure type comparison for independently declared structures that still might match types

Unify the 8 grammar productions for declaring variables. This greatly simplifies making changes for this set of productions.
...
This change also naturally picks up redeclarations of built-in arrays and the addition of the remaining linker objects of const, arrays, etc.

Add basic intra-stage linking validation for matching types and qualification of uniforms/ins/outs/globals, function body duplication, and mixing ES/non-ES shaders.
...
Still need to handle arrays and built-in redeclarations, and many more rules, but this puts the basics in place.

Test for and prevent any dead-code elimination, as all code is needed in the AST for static-use analysis.
