Hideto Ueno 567fce3ca2 [Attributor] Implement "norecurse" function attribute deduction ...

Summary:
This patch introduces `norecurse` function attribute deduction.

`norecurse` will be deduced if the following conditions hold:
* The size of SCC in which the function belongs equals to 1.
* The function doesn't have self-recursion.
* We have `norecurse` for all call site.

To avoid a large change, SCC is calculated using scc_iterator in InfoCache initialization for now.
