[LoopIdiom] Support 'shift until less-than' idiom (#95002)
The current loop idiom code for recognising and inserting a CTLZ
intrinsic does not support loops where the loopback control is based on
an unsigned less-than condition. This patch adds support for recognising
these loops and inserting a CTLZ intrinsic.
Fixes the missed optimization cases in #51064
