i965/fs: Helpers for un/shuffle 16-bit pairs in 32-bit components

This helpers are used to load/store 16-bit types from/to 32-bit
components.

The functions shuffle_32bit_load_result_to_16bit_data and
shuffle_16bit_data_for_32bit_write are implemented in a similar
way than the analogous functions for handling 64-bit types.

v1: Explain need of temporary in shuffle operations. (Jason Ekstrand)
