How else would I get str1? Using the below snippet, I only get str1.compare and str1->compare instead of str1.
Given a MemberExpr (str1.compare) is there an easy way to extract str1?
```
const auto StrCompare = cxxMemberCallExpr(
callee(cxxMethodDecl(hasName("compare"),
ofClass(classTemplateSpecializationDecl(
hasName("::std::basic_string"))))),
hasArgument(0, expr().bind("str2")), argumentCountIs(1),
callee(memberExpr().bind("str1")))
```
