This does not enable exception handlers yet, we still bail out in
MaglevCompiler::Compile if we have an exception handler table in
the bytecode array.

This CL:
- Generates code for exception handler blocks (which previously were
set as dead code)
- Creates a machinery for nodes to set the property CanThrow
- Reads the exception handler table from the bytecode array and
identifies if we're emitting nodes inside a try-block and for which
handler we should jump in case of an exception
- Generates an exception handler table for Maglev code
