[C++] Shift/stream operators considered arithmetic operators

[adepke]

What happened?

In C++, the shift operators >>, <<, >>=, and <<= should not be put in the same scope as basic arithmetic operators > and <. Instead, a new scope such as keyword.operator.shift.c should be introduced.

Example:

I think we have a keyword.operator.bitwise already.

the shift operators >>, <<, >>=, and <<= should not be put in the same scope as basic arithmetic operators > and <

> and < are not scoped as arithmetic operators however.
