No-one's going to clean up unused-but-set variable warnings in a

```
In file included from frameworks/compile/mclinker/lib/Target/AArch64/AArch64GOT.cpp:9:
In file included from frameworks/compile/mclinker/lib/Target/AArch64/AArch64GOT.h:15:
external/llvm/include/llvm/ADT/DenseMap.h:105:14: warning: variable 'NumEntries' set but not used [-Wunused-but-set-variable]
unsigned NumEntries = getNumEntries();
^
```
