Added support for CXXRewrittenBinaryOperator as a condition in ranged for loops. This is a new kind of expression, need to extend support for C++20 constructs. It fixes PR49970: range-based for compilation fails for libstdc++ vector with -std=c++20. Differential Revision: https://reviews.llvm.org/D104240
