Can anyone tell me how to get `ValueDecl` from `CXXThisExpr`? I cannot find any 
method return decl in 
https://clang.llvm.org/doxygen/classclang_1_1CXXThisExpr.html#details.
Thanks!

is addr_of operation allowed in lvalue?

In this code:
```
int arr[50];

#pragma omp target map(&arr)
  {}
```
We now reject `&arr` since `RE->IgnoreParenImpCasts()->isLValue()` return 
false. (RE is the expr of `&arr`)
