intel/compiler: implement is_zero, is_one, is_negative_one for 8-bit/16-bit

There are no 8-bit immediates, so assert in that case.
16-bit immediates are replicated in each word of a 32-bit immediate, so
we only need to check the lower 16-bits.

v2:
 - Fix is_zero with half-float to consider -0 as well (Jason).
 - Fix is_negative_one for word type.
