tree-optimization/97081 - fix wrong-code with vectorized shift
This corrects the mask for creation of x << s | x >> (-x & mask)
from a rotate x <<r s to use the precision of x.

PR tree-optimization/97081
* tree-vect-patterns.c (vect_recog_rotate_pattern): Use the
precision of the shifted operand to determine the mask.
* gcc.dg/vect/pr97081.c: New testcase.
