Florian Hahn a63b5c9e53 [CallSiteSplitting] Simplify isPredicateOnPHI & continue checking PHIs. ...

As pointed out by @thakis, currently CallSiteSplitting bails out after
checking the first PHI node. We should check all PHI nodes, until we
find one where call site splitting is beneficial.

This patch also slightly simplifies the code using BasicBlock::phis().
