Sampler allocation fix

Because samplers can be stored within structures, register allocation of entire structures within the samplers registers was pushing sampler indices outside of the allowed limit. In order to solve this, sampler registers now exclusively contain samplers, and utility functions to compute sampler only type size were added to make this possible.
