[RTL-ifcvt] PR rtl-optimization/68624: Clean up logic that checks for clobbering conflicts across basic blocks

PR rtl-optimization/68624
* ifcvt.c (noce_try_cmove_arith): Check clobbers of temp regs in both
blocks if they exist and simplify the logic choosing the order to emit
them in.

* gcc.c-torture/execute/pr68624.c: New test.
