f5dcdf0123 Front-end: Don't lower precision of bit operations taking highp inputs. 
See issue #350 for detail.  This may be an ESSL specification issue.

9c56d84b73 Use proper precision qualifiers for bitfield build-in functions on ES 
This change causes ES shaders to precision qualifiers for build-in functions as defined in ESSL spec. It especially mattersfor functions that are defined as highp or taking a highp.

Fixes vulkanCTS dEQP-VK.glsl.builtin.function.integer.bitfieldreverse.*, where bitfieldReverse() retval was wrongly marked as RelaxedPrecision.

Note: floatBitsToInt/floatBitsToUInt precision is also broken, but in different way - so it is not addressed here.

17f0786418 Parser: Precise: Recognize 'precise', tag types, and do related semantic checking. 
This partly overlaps pull request #222, we have divided the work on this one.

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.

6373574b13 Front-end: Fix: Cubemap arrays only use 3-component coord when accessed as an image. 
4 components are needed when used a texture, but not an image, which multiplies
layers and faces into the same coordinate.  This fixes it from using 4 everywhere,
to only using 4 for textures and 3 for images.

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.

65c78a0b62 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.
