This eliminates a conditional on that path, and ensures ICmpInst/FCmpInst
both have an out-of-line virtual method to home the class.

"True Loop" and "False Loop" naming terminology to refer two loops
after loop cloning is confusing. Instead just use A_Loop and B_Loop.

Starting value of second loop's induction variable can not be lower 
then starting value of original loop's induction variable.

use the ValueType name instead of the llvm type name, to match what the
verifier expects. For integers these are the same, but for floating-point
values the intrinsics use f32/f64 instead of float/double.
