replace gnu c statement expressions

struct fpu {
  int last_cpu
};
int *current_task, *prev_p, *next_p;
int switch_fpu_prepare_cpu;
long foo_pfo_val__;
void minimal_fpu_save();
void foo() {
  int *__trans_tmp_7 = ({
    ({
      asm("movq %%gs:%[var], %[val]"
          : [val] "=r"(foo_pfo_val__)
          : [var] "p"(&current_task));
      (int *)foo_pfo_val__;
    });
  });
  if (__trans_tmp_7) {
    struct fpu *old_fpu = prev_p;
    minimal_fpu_save(prev_p);
    old_fpu->last_cpu = switch_fpu_prepare_cpu;
  }
}

Can become:

struct fpu {
  int last_cpu
};
int *current_task, *prev_p, *next_p;
int switch_fpu_prepare_cpu;
long foo_pfo_val__;
void minimal_fpu_save();
void foo() {
  asm("movq %%gs:%[var], %[val]"
          : [val] "=r"(foo_pfo_val__)
          : [var] "p"(&current_task));
  if (foo_pfo_val__) {
    struct fpu *old_fpu = prev_p;
    minimal_fpu_save(prev_p);
    old_fpu->last_cpu = switch_fpu_prepare_cpu;
  }
}

Thank you for the suggestion!
