Reviewed by Mike Wyrzykowski.

In our current implementation, statements that need to be semicolon-terminated
(such as variable declarations, assignments, etc) emit their semicolons and
newline directly in its own serialization code. That is a problem, since statements
can appear in places where we can't emit the semicolon, such as in for-loops'
init and update clauses. The main place statements appear, and where it's necessary
to print the semicolons (and nice to print newlines) is in a CompondStatement, so
this patch changes the serializztion of compound statements to print the semicolon
and new-line after its nested statements as necessary.
