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.

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.

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.)

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.

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.

Array of array: Implement the core functionality: types, constructors, operations.
...
There will be subsequent commits to refine semantics, esp. version-specific semantics,
as well as I/O functionality and restrictions.
Note: I'm getting white-space differences in the preprocessor test results,
which I'm not checking in. I think they need to be tagged as binary or something.

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.
