bmeurer d3e5db0428 [compiler] Always pass closure argument to with, catch and block context creation. 
Up until now we sometimes pass Smi 0 around as closure and expect the
runtime to translate that appropriately. But we need to be careful in
some places to not confuse the Smi 0 with a real closure. However, we
could instead just pass the correct closure extracted from the native
context.

This addresses three long-standing TODOs in the JSTypedLowering pass.

Drive-by-fix: Further unify error message reporting for ToObject (we had
a special message in case of ToObject error in with context creation).
