[PATCH] D39507: [AArch64] Fix the number of iterations for the Newton series

[Evandro Menezes via Phabricator via llvm-commits]

The number of iterations was incorrectly determined for DP FP vector types and the tests were insufficient to flag this issue.

Probably the releases 4 and 5 of LLVM should also be fixed.
