Problem
#111 introduced a regression where ArgumentError exceptions during filtering aren't getting translated to Liquid::ArgumentError in the Liquid::Variable#render when it contains a Liquid::C::Expression. This exception handling isn't normally needed for Liquid::C::Expression, so it was only being done for Liquid::C::BlockBody#render_to_output_buffer, but it is needed if we are doing filtering.
Solution
Introduce a Liquid::C::VariableExpression class that inherits from Liquid::C::Expression and wraps the evaluate method with a rescue handler to translate the ArgumentError exceptions into Liquid::ArgumentError.
