Setting component=0 is later taken to mean the shader did so, which
is not always legal. It should instead set the component as not set
by the shader.

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.

Fixes issue #610. Also provides a testing option to keep uncalled functions.

Partially addresses issue #513.

Fixed off-by-one error with gl_MaxClipDistances and similar limits.

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.

Fix two multi-sample bugs: 1) include MS in name mangling, 2) add 'sample' argument texelFetch(*MS*,...).

glslang: Formally track all built-in variables, right from the beginning, to enable avoiding all textual compares at any subsequent stage in the stack.  (To be used in future check ins.)

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.

Implement GL_ARB_shader_texture_image_samples.  Also add in gl_MaxSamples and the float imageAtomicExchange.

Finish virtually all of the remaining atomic counter functionality.  Still need offset collision detection.

Implement GL_ARB_shader_image_load_store.  Partly done (format layout qualifiers) from a submission.

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.

GL_ARB_enhanced_layouts, final.  #extension tests, built-in constants, and bug fix for non-constant expression in layout(...=expr).

GL_ARB_enhanced_layouts, part 2:  Full implementation of location/component, plus the parsing for xfb* and align/offset (but not yet full semantics for align/offset).

 - 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.

 - print out block member types when printing a block (makes all test results change)
 - const versions of all intermediate.h type-identification methods
 - layoutSlotLocation -> layoutLocation

 - array size limit checking
 - illegal member qualifiers
 - additional members

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 some missing invariant semantic checks, replace some misplaced sampler semantic checks, add parameter and structure member checks against new qualifiers.

Note: lots of test results changed due to listing the members of a block when printing types.

Tie "location = " to the right stages/versions/extensions.  Also add "#define extension 1" extension support and instructions.
