INTEL_shader_integer_functions2: Add compiler front-end support

The changes to glslang/glslang/MachineIndependent/ParseHelper.cpp exist purely to prevent even more instances of "warning: enumeration value ‘EOp...’ not handled in switch" v2: Remove 8-bit types. Overzealous copy-and-paste led to adding support for a bunch of types that the extension doesn't actually enable. v3: Update expected test results file. Just changing an expected results file to make a test pass seems sketchy to me, but I'm not sure what else to do. v4: Add missing entry for EOpAbsDifference in TOutputTraverser::visitBinary. Noticed by JohnK.
