Change the way replaceInstructions work when using multiple instructi…

…ons.

Currently it looks like if you have a target in the following style:
indices = [1,5,7]
replaceInstructions = [Ldc_i4_0, Ldc_i4_1, Ldc_i4_2]
It will actually do the following in replaceInstructions:

var index = indices[1]; //Index = 5
instructions[index] = replaceInstructions[index] //We don't have 5 replace instructions! only 3 because we specified 3 indices!

The change will make it so that if you replace instructions at (For example) 1, 7, 10 it will just ask for the new instructions at index 0, 1 and 2.
