Florian Hahn d67c5eca12 [LoopUnroll] Add support for loops with exiting headers and uncond latches. 
This patch generalizes the UnrollLoop utility to support loops that exit
from the header instead of the latch. Usually, LoopRotate would take care
of must of those cases, but in some cases (e.g. -Oz), LoopRotate does
not kick in.

Codesize impact looks relatively neutral on ARM64 with -Oz + LTO.
