pp_hot.c:pp_aassign: mortalise variable only if we have to

This affects the hash-assignment path.

Don’t mortalise the value to protect it from a magical key making the
hv_store_ent call die, as that could unduly extend the mortals stack.

Instead, copy the key if it is magical.

Based on a patch by Ruslan Zakirov.
