…osing function when a nested function is declared in the param scope of that enclosing function. This an result in us calculating incorrect envIndex for any symbols captured from enclosing scopes if this skipped body scope appears in the frameDisplay being passed to the nested function. This fix addresses the issue by marking the parameter scope also as mustInstantiate = true so we end up computing the correct envIndex. This problem and the fix only triggers when the enclosing function's param and body scopes are merged so the param and body scopes will never appear together in the scope stack and as such will not mess up the envIndex.

…s temporary during an implicit call, to prevent objects stored on the stack to be used outside of the function. This is done by preventing removal of the Bailout instruction for that case during the DeadStore pass of GlobOpt.
