x32: Update gcc.target/i386/builtin_thread_pointer.c

Update gcc.target/i386/builtin_thread_pointer.c for x32.  For

int
foo3 (int i)
{
  int* p = (int*) __builtin_thread_pointer ();
  return p[i];
}

we can't generate:

	movl	%fs:0(,%edi,4), %eax
	ret

for x32 since the address of %fs:0(,%edi,4) is %fs + zero-extended to 64
bits of 0(,%edi,4).  Instead, we generate:

	movl	%fs:0, %eax
	movl	(%eax,%edi,4), %eax

	PR target/96955
	* gcc.target/i386/builtin_thread_pointer.c: Update scan-assembler
	for x32.
