[SLP] Optimize stacksave dependence handling [NFC]
After writing the commit message for 4b1bace28, realized that the mentioned optimization was rather straight forward. We already have the code for scanning a block during region initialization, we can simply keep track if we've seen a stacksave or stackrestore. If we haven't, none of these dependencies are relevant and we can avoid the relatively expensive scans entirely.
