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

420Pack:  Implement length() on vectors and matrices.  Also, tweak line-continuation semantics to understand the extension.

Allow the pre-150 built-in redeclarations when using SSO: gl_Position, gl_PointSize, gl_ClipVertex, and gl_FogFragCoord.

Correct which versions can support the extensions GL_ARB_separate_shader_objects and GL_ARB_shading_language_420pack.  They'd only gone back to 150, rather than 130/140.

 - 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

Added constant folding for relational (e.g. lessThan) built-ins, relational built-ins for uints, and bitwise ops for mixed scalars and vectors.

Also, allow comments to precede "#version 100".

Complete hook up all the compile/link errors to the command-line exit status. (Also, an updated test left from the last check-in.)

Stop emitting the "#version missing" warning, and hook up the existing "suppress warnings" to a command-line option (-w).

Clean up/resolve a bunch of TODO, which included implementing pixel_center_integer and origin_upper_left and adjusting what versions see legacy texturing names.

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.

For all keywords already present, get correct when they could be identifiers, are reserved words, or are keywords, for all versions of ESSL and GLSL.
