GetRegForReload() now keeps track which registers have been considered and rejected during its quest to find a suitable reload register. This avoids an infinite loop in case like this:
...
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
sees r1 is taken by t2, tries t2's reload register r0
sees r0 is taken by t3, tries t3's reload register r1
sees r1 is taken by t2, tries t2's reload register r0 ...

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.

Clean up some code around the store V, (cast P) -> store (cast V), P

transform. Change some variable names so it is clear what is source and

illegal casts from being formed and catches bitwidth bugs sooner.
