re PR tree-optimization/65014 (ice with error: type mismatch in shift expression)
PR tree-optimization/65014
* fold-const.c (fold_binary_loc): When creating {L,R}ROTATE_EXPR,
use original second operand of arg0 or arg1 instead of
that adjusted by STRIP_NOPS.
* gcc.c-torture/compile/pr65014.c: New test.
