Add stack traces to error objects.
...
Revert 'add context and flag argument to js_newstate' commit.
The context argument just adds clutter. The flag which was intended
for JS_DEBUG and/or JS_STRICT shouldn't be necessary.
js_newcfunction and js_newcconstructor need an extra argument, the
name of the function to use in stack traces.

Add stack and scope balancing to exits from try/catch blocks.
...
Because finally blocks are inlined, their break and continue instructions
are duplicated so we need to use a list of jumps to patch instead of
a single instruction and target pointer.
Also save the top return value from the stack, since an interrupted
return (return out of a try block that has a finally with another
jump or return) will leave multiple return values on the stack.
