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.

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.)

af459216a1 Correct precision qualification on built-in functions.
This is a replacement commit for pull request #238.

This is a design change, followed by implementation change that
A) fixes the changes caused by the design change, and
B) fixes some cases that were originally incorrect.

The design change is to not give built-in functions default precision qualification.
This is to allow the rule that the precision of some built-in functions adopt their
precision qualification from the calling arguments.  This is A above.

A consequence of this design change is that all built-ins that are supposed to have
an explicit precision qualifier must now be declared that way.  So, a lot more
built-in declarations now have precision qualifiers, just to keep things the same.
This is B above.

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.

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.

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.

f2ee3dd46a 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
