[cfe-dev] ForStmt: test if loop cond is true on first iteration

[Panke]

Given this for loop:

--
unsigned x;
for(x = 0; x < SOME_CONSTANT_EXPR; ++x) { ... }
--

How can I test if the condition 'x < SOME_CONSTANT_EXPR' is true for the
first iteration of this loop? Can I somehow (easily) substitute all
occurences of 'x' with 0 and call i.e. Expr::evaluateAsBool() on it?
