Removes UpRefVisitor from ControlFlowAnalyzer, which scans the whole
program to find extra methods that need rescuing due to virtual
method calls.  Instead, such methods are now checked at the
time a new method or type becomes instantiable.

Also, adds PerfLogger calls to GWTCompiler, to make it easy to time
an entire compile.
