Should we be worried about macros here?
It looks a bit like we're ignoring macros entirely for this check, so maybe
that can be done as a separate patch instead. The situation I am worried about
is:
```
#if SOMETHING
#define INIT ""
#else
#define INIT "haha"
#endif
std::string S = INIT;
```

namedDecl(
- varDecl(
- hasType(hasUnqualifiedDesugaredType(recordType(
- hasDeclaration(cxxRecordDecl(hasStringTypeName))))),
- hasInitializer(expr(ignoringImplicit(anyOf(
- EmptyStringCtorExpr, EmptyStringCtorExprWithTemporaries)))))
- .bind("vardecl"),
+ varDecl(StringType, hasInitializer(EmptyStringInit)).bind("vardecl"),
unless(parmVarDecl())),
----------------
Should this also match on something like `std::string foo{};` as a redundant
init? Similar question for the other cases. (Could be done in a follow-up patch
if desired.)
