[analyzer] Memoize complexity of SymExpr
Summary:
This patch introduces a new member to SymExpr, which stores the symbol complexity, avoiding recalculating it every time computeComplexity() is called.
Also, increase the complexity of conjured Symbols by one, so it's clear that it has a greater complexity than its underlying symbols.
