Hi,
I think it will be more beautiful to adjust indentation of statements with more than one lines.
In function TreeTransform<Derived>::TransformDependentScopeDeclRefExpr
the second line of statement
NestedNameSpecifierLoc QualifierLoc \newline = getDerived().TransformNestedNameSpecifierLoc(E->getQualifierLoc());
is no more indent than the first line
There is a similar case in function TreeTransform<Derived>::TransformUnresolvedMemberExpr
Also I use clang-format to fix above functions
Thanks alot
