PR tree-optimization/59387
* tree-scalar-evolution.c: Include gimple-fold.h and gimplify-me.h.
(scev_const_prop): If folded_casts and type has undefined overflow,
use force_gimple_operand instead of force_gimple_operand_gsi and
for each added stmt if it is assign with
arith_code_with_undefined_signed_overflow, call
rewrite_to_defined_overflow.
* tree-ssa-loop-im.c: Don't include gimplify-me.h, include
gimple-fold.h instead.
(arith_code_with_undefined_signed_overflow,
rewrite_to_defined_overflow): Moved to ...
* gimple-fold.c (arith_code_with_undefined_signed_overflow,
rewrite_to_defined_overflow): ... here. No longer static.
Include gimplify-me.h.
* gimple-fold.h (arith_code_with_undefined_signed_overflow,
rewrite_to_defined_overflow): New prototypes.
* gcc.c-torture/execute/pr59387.c: New test.
