Thanks.

Fixed up the as_a_nullable to safe_as_a, and committed to trunk as
r214170, having verified bootstrap&regrtest on x86_64-unknown-linux-gnu
(Fedora 20) albeit in combination with patches 9-29 [1], and verified
that it builds standalone with 9 targets.

Am attaching what I committed.

FWIW these functions become a macro again in patch #173.
