`move_val_init` signature change broke freebsd32 build

[jashank]

I don't quite understand what's going on here, but it looks like intrinsics changed under us. From freebsd10_32 build 151:

rustc: i686-unknown-freebsd/stage0/lib/rustlib/i686-unknown-freebsd/lib/libcore
../src/libcore/intrinsics.rs:190:9: 190:50 error: intrinsic has wrong type: expected `unsafe extern "rust-intrinsic" fn(&mut P0, P0)`: expected &-ptr, found *-ptr [E0211]

This may also be blocked-by/blocking-a FreeBSD i386 snapshot.
