move OP_MUL simplification in a separate function
This patch contains no functional changes.
It just moves the code for simplification of OP_MUL{U,S} with
constant operands in its own function in preparation for some
additional simplifications coming in the same serie.
Also add some test cases for the concerned simplifications.
