Adds RuntimeStats counters for HeapBrokerInitialization, Serialize, SerializeMetadata and Finalization phases. These happen only on main thread. In a followup cl we will also add counters for other phases that could happen on main thread or background thread. Earlier RecompileSynchronous was used to measure the time spent in Concurrent, non Concurrent and Concurrent finalize phases. This cl replaces them with OptimizeConcurrent, OptimizeNonConcurrent and OptimizeConcurrentFinalize counters. This cl also renames RecompileConcurrent to OptimizeBackground to make it clear this measures the background component of optimization. This also updates names of trace events to be in-sync with RuntimeStat counters.

Leszek Swirski authored
During conflict lookup (for lexical variables and sloppy block function hoisting), we cache the looked-up variable on the current scope if the lookup goes through a ScopeInfo. However, for variable lookup during scope analysis, we use the "entry point" as the cache. Since both lookups can create Variables, this can cause us to create duplicate variables, e.g. a duplicate function name variable in the attached test. Instead, for ScopeInfo conflict lookups we can cache the result on the function's outer scope, which shoud be equivalent to the entry point. As a (necessary) drive-by, we can terminate the lookup early if we find a VAR with the same name, as we can safely assume that its existence means that it doesn't conflict, which means that our variable can't conflict either.

FunctionBlueprint holds a SharedFunctionInfo, FeedbackVector and a Hints object that represents what we know about the Context of the "function-to-be." Since we occasionally synthesize a FunctionBlueprint object from a JSFunction (when we have it), it can happen that sometimes the Context hint is a concrete Context object, and other times it's a VirtualContext, representing a context created sometime during the bytecode execution of the function under optimization. Moreover, both such FunctionBlueprints can exist in the same run due to the vagaries of CALL_IC feedback (ie, sometimes you have a JSFunction, other times you don't).
