Subject: [PATCH] fix new issue for global variables

1. The w2ll will crash if compile the code like that:
```
int sre_random(void)
{
  long  rnd1;
  static long  tbl[64];
  int i;
  for (i = 0; i < 64; i++) {
        tbl[i] = rnd1;
        if (tbl[i] < 0)
                tbl[i] += 0;
  }
  return 0;
}
```

2. Error Log:
```
w2ll: /workspace/toolchain/llvm/llvm/lib/IR/Globals.cpp:472: void llvm::GlobalVariable::setInitializer(llvm::Constant*): Assertion `InitVal->getType() == getValueType() && "Initializer type must match GlobalVariable type"' failed. (xcalcc:571)
```
