spirv-fuzz: Create synonym of int constant using a loop (#3790)

This transformation, given a constant integer (scalar or vector) C,
constants I and S of compatible type and scalar 32-bit integer constant
N, such that C = I - S*N, adds a loop which subtracts S from I, N
times, creating a synonym for C.

The related fuzzer pass randomly chooses constants to which to add
synonyms using this transformation, and the location where they should
be added.

Fixes #3616.
