Say the original code is int bx = blockIdx.x, I already found the
MemberExpr of this line of code, which is blockIdx.x. But all I have is
only this MemberExpr. What I need is the actual string representation of
this MemberExpr so that I can perform the string comparison to make sure
that this MemberExpr is indeed blockIdx.x, and perform the rewriting
