Restore strict refs on stashes, removed by ce10b5d1ec5b5f68b0811018a415bc37.

Strictures on stashes were special-cased, because the lexer was special-cased
to avoid autovivifying stashes (in adc51b978ed1b2e9d4512c9bfa80386ac917d05a,
now reverted), to keep the behaviour of defined %stash:: consistent.

defined %stash:: is deprecated.

Keep the new regression tests from ce10b5d1ec5b5f68b0811018a415bc37bb6bfe5e.
