re PR c/58943 (wrong calculation of indirect structure member arithmetic via function call)
PR c/58943
* c-typeck.c (build_modify_expr): For lhs op= rhs, if rhs has side
effects, preevaluate rhs using SAVE_EXPR first.
* c-omp.c (c_finish_omp_atomic): Set in_late_binary_op around
build_modify_expr with non-NOP_EXPR opcode. Handle return from it
being COMPOUND_EXPR.
(c_finish_omp_for): Handle incr being COMPOUND_EXPR with first
operand a SAVE_EXPR and second MODIFY_EXPR.
* gcc.c-torture/execute/pr58943.c: New test.
* gcc.dg/tree-ssa/ssa-fre-33.c (main): Avoid using += in the test.
