[Mesa-dev] [RFC PATCH 29/65] tgsi: add new Bindless flag to tgsi_instruction_texture

Old-style images are identified using TGSI_FILE_SAMPLER, but
bindless samplers can be TGSI_FILE_CONSTANT or TGSI_FILE_TEMPORARY.
To avoid backend compilers to be confused, this adds a new flag
that will only be set for bindless samplers.
