glsl: parse invocations layout qualifier for ARB_gpu_shader5
_mesa_glsl_parse_state in_qualifier->invocations will store the invocations count. v3: * Use in_qualifier to allow the primitive to be specied separately from the invocations count (merge_qualifiers) Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Anuj Phogat <anuj.phogat@gmail.com>
