Fold ternary and comma ops only after parsing is done In case folding a ternary op or a comma op would change the qualifier of the expression, the folding is deferred to a separate traversal step. After this there are no more cases where the type of a TIntermSymbol node needs to differ from the type of the variable it is referring to. There are still some cases where some parts of TIntermSymbol type are changed while keeping the TVariable type the same though, like when assigning array size to gl_PerVertex nodes or sanitizing qualifiers of struct declarations.
