Update style of bounds checking on/off Expr's based on Julia verison number.

Use embedded functions of the form ParallelAccelerator.ParallelIR.function_name rather than generating
expressions with Base.getfield(ParallelAccelerator.ParallelIR, :function_name) because this form has a module
appearing in the AST and this causes an error when the AST is later deepcopied.
