ba5cc2fafa GLSL: Fix #822: Improve information given for syntax errors. 
Also, fixed one test file that didn't have its syntax error as the last line.

71c100d7c0 GLSL output: Removed fixed-size buffer; fixes #769. 
Makes some white-space differences in most output, plus a few cases
where more could have been put out but was cut short by the previous
fix-sized buffer.

906cc21816 Linker: Eliminate uncalled functions, because they can be ill-defined. 
Fixes issue #610. Also provides a testing option to keep uncalled functions.

d3f1122a44 Whole stack: Fix stale types in the AST linker object nodes, fixing #557. 
Rationalizes the entire tracking of the linker object nodes, effecting
GLSL, HLSL, and SPIR-V, to allow tracked objects to be fully edited before
their type snapshot for linker objects.

Should only effect things when the rest of the AST contained no reference to
the symbol, because normal AST nodes were not stale. Also will only effect such
objects when their types were edited.

f6640761c4 Front-end: Implement 2nd task of issue #400; precision of result and operation. 
From the ES spec + Bugzilla 15931 and GL_KHR_vulkan_glsl:
- Update precision qualifiers for all built-in function prototypes.
- Implement the new algorithm used to distinguish built-in function
  operation precisions from result precisions.
Also add tracking of separate result and operation precisions, and
use that in generating SPIR-V.
(SPIR-V cares about precision of operation, while the front-end
cares about precision of result, for propagation.)

21f1286f57 Front-end: Implement GL_EXT_shader_non_constant_global_initializers. 
This lets ES shaders use non-constant initializers for non-constant globals.

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.

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.

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.

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.
