      MIPS: Switch full-codegen from StackHandlers to handler table. · 03620298
      balazs.kilvady authored 
      Port 38a719f9

Original commit message:
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).
