Implement MUBUF instructions for shorts/bytes (#2856)

Browse Source 
* implement loads/store instructions for types smaller than dwords

* initialize s16/s8 types

* set profile for int8/16/64

* also need to zero extend u8/u16 to u32 result

* document unrelated bugs with atomic fmin/max

* remove profile checks and simple emit for added opcodes
