/**
* Given two Value-based instructions this will firstly check if
* at least one of the two is of type Pointer, then checks if the
* remaining instruction is an of type Integer - the remaining instruction
* will then be coerced into a pointer.
*
* If both are Pointers, neither are pointers or one or the other is
* a Pointer and another is non-Integer then nothing will be coerced.
* and this function is effectively a no-op.
*
* Params:
* vInstr1 = the first instruction
* vInstr2 = the second instruction
