c55510cb36 Inline context initialization & improve _object.value 
* Context setup is now done via _newContext.
* _newContext is a function that resides in inline.go. _newContext is very flat,
resulting in almost no function calls (a 180 from the earlier status quo).
* inline.go is a Go source file that is built by Perl (via inline).
* Lots of crufty functions removed (along with all of their TODO & FIXME).
* In addition, before, the underlying value of _object.value was a pointer to
something. This made for extra work, since the type of _object.value is interface{},
which is already something of a pointer. Now, the underlying value of _object.value
in Function, Date, RegExp, ..., is a struct value.
* type_function.go was streamlined, removing superfluous struct fields and methods.
* There is now less "digging" to get to the actual value of a function, which is important
when makings lots of calls.

Before (without inline):

After (with inline):

321cc0dca8 Add _argumentsStash, with better conforming arguments behavior: 
1. Can not delete a function parameter
    2. Deleting the index of an arguments object simply
       removes the link to that function parameter

4e4e89c894 Fix bug in String.slice with a (go) slice bounds violation 
Basically, check that start is less than length before trying
to take a slice.

Also, rename valueToArrayIndex to valueToRangeIndex to reflect
the fact that it does not always return a value that is valid
index (value could be length)
