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