Reapply "[ValueTracking] Propagate sign information out of loop" (#182512)
LLVM converts sqrt libcall to intrinsic call if the argument is within
the range(greater than or equal to 0.0). In this case the compiler is
not able to deduce the non-negativity on its own. Extended ValueTracking
to understand such loops.

Have created new ABI's for matching Intrinsics with three operands
(those existed only for 2 operands)
`matchSimpleTernaryIntrinsicRecurrence` and `matchThreeInputRecurrence`.
