[PATCH] forwprop: Pattern recognize more rotates [PR94344]

Hi! The following patch adjusts simplify_rotate to recognize more rotates, basically we allow even some same precision integral -> integral conversions, with the requirement that the RSHIFT_EXPR operand has to be done in unsigned type (i.e. logical right shift), so that we compensate for the combi
