memory.c: Prevent garbage collection when running out of memory.

When running out of memory, garbage collection would free lists and
dictionaries that are not yet referenced. This would later on lead to
a use-after-free for these objects.

Releated to vim-patch:7.4.916, so also updating version.c.
