Populate gl_InstanceID attribute information explicitly While compiling ESSL1 shaders, with the compiler having both SH_INITIALIZE_BUILTINS_FOR_INSTANCED_MULTIVIEW and SH_VARIABLES set, variable collection terminates with an assertion failure. The reason behind this is that SH_INITIALIZE_BUILTINS_FOR_INSTANCED_MULTIVIEW adds gl_InstanceID to the AST to initialize the multiview builtins, but the variable collection pass cannot find gl_InstanceID information in the symbol table because the builtin is only available in ESSL 3.00 and greater. To address this the patch populates the gl_InstanceID attribute information explicitly in the variable collection pass instead of retrieving it from the symbol table.
