Implement gather/scatter operations for shader register files.

This allows to address the registers with a vector of indices.

Also rename 'dynamic' register files to 'indirect addressable', to
disambiguate from 'dynamic indexing' at the shader level. Indexing with
a uniform does not require gather/scatter operations, but does require
indirect addressing.
