Daniel Clifford 27dc9fa5ca Reland "[torque]: Implement catch handlers for try blocks" 
This is a reland of 0f15ed05b9

Original change's description:
> [torque]: Implement catch handlers for try blocks
> 
> In addition (and in combination), try statements now support "catch"
> clauses at the end that catch JavaScript exceptions throw by any builtin
> or runtime function contained in the try block:
> 
>   try {
>     ThrowTypeError(context, ...);
>   }
>   catch (e) {
>     // e has type Object
>   }
>
