Optimization | Modify Add (Integer) Instruction to use LEA instead. (#1971)

Browse source 
* Optimization | Modify Add Instruction to use LEA instead.

Currently, the add instruction requires 4 registers to take place. By using LEA, we can effectively perform the same working using 3 registers, reducing memory spills and improving translation efficiency.

* Fix IsSameOperandDestSrc1 Check for Add

* Use LEA if Dest != SRC1

* Update IsSameOperandDestSrc1 to account for Cases where Dest and Src1 can be same for add

* Fix error in logic

* Typo

* Add paranthesis for clarity

* Compare registers as requested.

* Cleanup if statement, use same comparison method as generateCopy

* Make change as recommended by gdk

* Perform check only when Add calls are made

* use ensure sametype for lea, fix else

* Update comment

* Update version #
