GLSLangSpec.4.60.pdf missing subpassinput in Gramma definition

[darkyellow]

This is probably in other versions of the glsl spec too but when processing the gramma definitions in the 4.6 spec there is no mention of the subpassInput and subpassInputMS keywords in the token list returned from lexical analysis and this no mention of it in the shading language gramma.

Is it just a case of creating the right tokens and adding to type_specifier_nonarray: ?

This is an issue in the GLSL language spec rather than in the compiler, so I'm transferring this to the GLSL repository.
