Why are you introducing another member variable here? Why don't you keep
using ParameterIds? What is the this variable supposed to track?

[LLVMdev] [Polly] Analysis of the expensive compile-time overhead of Polly Dependence pass
Hi Sebastian,
Recently, I found the "Polly - Calculate dependences" pass would lead to significant compile-time overhead when compiling some loop-intensive source code. Tobias told me you found similar problem as follows:
http://llvm.org/bugs/show_bug.cgi?id=14240
My evaluation shows that "Polly - Calculate dependences" pass consumes 96.4% of total compile-time overhead

A lot of Polly functions access ParameterIds and Parameters using existing ScevExpr. If we create new ScevExpr and put them into Parameters and ParameterIds, it may require some extra tricks to handle the mapping from existing ScevExpr to newly created ScevExpr. I think we can consider fixing it later.
