This switches full-codegen to no longer push and pop StackHandler markers onto the operand stack, but relies on a range-based handler table instead. We only use StackHandlers in JSEntryStubs to mark the transition from C to JS code. Note that this makes deoptimization and OSR from within any try-block work out of the box, makes the non-exception paths faster and should overall be neutral on the memory footprint (pros). On the other hand it makes the exception paths slower and actually throwing and exception more expensive (cons).
