Fix ref vars for --no-local and gasnet

[reviewed by brad/sung]

I originally hadn't tested reference variables with no-local or gasnet,
loosening an ASSERT in parallel.cpp was all that was needed to make them
work.

Remove some unused flags from flags_list.h.

Flags FLAG_CALLS_CONSTRUCTOR and FLAG_NO_FORMAL_TMP are not currently used, so may be
removed from the flags_list.h.
