39974acf93 ESSL 1.0: Add GL_FRAGMENT_PRECISION_HIGH to ESSL 1.0. It was in desktop, and properly not in ES 3.0, but missing in ES 1.0. 
git-svn-id: https://cvs.khronos.org/svn/repos/ogl/trunk/ecosystem/public/sdk/tools/glslang@25175 e7fa87d3-cd2b-0410-9028-fcbf551c1848

b76d6d6496 GL_ARB_enhanced_layouts, part 1: Track whether constants are literals, to enable version-specific checking of layout(... = literal) vs. layout(... = expression).

7cbfdf4394 Minor infrastructure changes, to simplify an upcoming check in: 
- 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

623833fabc Tessellation partial implementation (not ready for use yet), including: 
- the built-in constants
 - built-in variable declarations, some dependent on gl_MaxPatchVertices
 - layout qualifier for vertices (shared with geometry shader max_vertices)
 - layout qualifiers for vertex spacing, vertex order, point mode, and primitive type
 - link semantics for layout qualifiers

Still TBD:
 - patch qualifier and arrayed input handling
 - sizing of gl_out[]
 - additional semantic checking
 - supporting the extension on version 150

d6bef9186b Correct textureGather*() extension support: 
- add extension behavior and warning message for partial extension support
 - add partial support for gpu_shader5 for textureGather*
 - add interactions between texture rectangle and textureGather*
 - add checks to distinguish between gpu_shader5 and texture_gather extension feature differences

5f1a0b7998 Eliminate flex as the GLSL lexical analyzer, going from two nested lexical analyzers down to one, leaving just the preprocessor's lexical analysis. A new layer replaces it, to translate from the preprocessor's view of tokenization to glslang's view of tokenization. 
Also:
 - change source locations from an int to TSourceLoc (shader number, line number) throughout
 - various improvements to the preprocessor

9fd55bd338 Add a new shader-versioning infrastructure capable of handling multiple profiles, desktop/ES, many versions, features coming and going in different versions across different profiles, and extensions. 
NB: *Use* of this infrastructure is so far only skeletal.

Fixed a few typos and minor issues along the way.
