We only want to do this if the src and destination types have the same

We not align the final stack slot but instead let the target do so in emitPrologue(). Each target can make adjustments to the stack frame and re-align the stack as it deem appropriate. Do not align it twice which can end up wasting stack space.

t1 := op t2, t3
t2 <- assigned r0 for use by the reload but ended up reuse r1
t3 <- assigned r1 for use by the reload but ended up reuse r0
t1 <- desires r1

For PR1043:

This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*
This also fixes PR1120.
