    tree-optimization: Handle variable trip count XOR in final value replacement [PR112104]

---
extern signed char a;
signed char
func (int i, int j)
{
  signed char c = 0;
  while (i != 0)
    {
      a ^= j;
      ++c;
      ++i;
    }
  return c;
}

is optimized to:

	testl	%edi, %edi
	je	.L3
	movl	%edi, %eax
	andl	$1, %edi
	negl	%edi
	negl	%eax
	andl	%esi, %edi
	xorb	%dil, a(%rip)
	ret
.L3:
	xorl	%eax, %eax
	ret

add check-function-bodies to gcc.target/i386/pr92080-12.c to check for
optimized codegen.

	PR tree-optimization/112104
	* gcc.target/i386/pr92080-12.c: Remove scan-assembler-times and
	add check-function-bodies to check for optimized codegen.
