The tracelet region selector now supports creating regions with inlined calls. When it sees an FCall with a known callee, it invokes a new instance of the tracelet region selector on the callee. The callee is evaluated using the same cost metric as Translator::analyze. If it passes, the callee is inlined for real, which allows creation of longer tracelets based on the return value from the callee. Differential Revision: D909359
