Fix ICE in vectorizable_nonlinear_induction with bitfield.

 if (TREE_CODE (init_expr) == INTEGER_CST)
    init_expr = fold_convert (TREE_TYPE (vectype), init_expr);
  else
    gcc_assert (tree_nop_conversion_p (TREE_TYPE (vectype),
                                       TREE_TYPE (init_expr)));

and init_expr is a 24 bit integer type while vectype has 32bit components.

The "fix" is to bail out instead of asserting.

gcc/ChangeLog:

PR tree-optimization/112496
* tree-vect-loop.cc (vectorizable_nonlinear_induction): Return
false when !tree_nop_conversion_p (TREE_TYPE (vectype),
TREE_TYPE (init_expr)).

gcc/testsuite/ChangeLog:

* gcc.target/i386/pr112496.c: New test.
