If allow_string_plus is set to false, the compiler will report an error
when it finds a string literal followed by +. Invoking the + operator on a
string value throws a noSuchMethod exception.
This is temporary code that we'll eliminate once the + operator on
strings is completely removed.

An empty regular expression had caused split to loop infinitely. Now,
the split method behaves like its namesake in ECMAScript and splits a
string along character boundaries.
The split, replaceFirst, and replaceAll methods only supported RegExp
and String patterns. Now, these methods are implemented on top of the
allMatches method and work for all subinterfaces of Pattern.

External strings refer to character data in memory located outside of
the managed heap. This memory is considered to be owned by the
embedding application. To help with the management of external
memory, the virtual machine allows the embedding application to
register for a "death notice" when an external string object is
garbage collected. A death notice takes the form of a callback
invoked by the garbage collector with the address of the external
memory. Death notices will be implemented in the garbage collector by
future commit.
