Force IFN_LOAD/STORE_LANES operands to be memory (PR91577)
This patch uses the workaround Richi suggested in the PR: make
discover_nonconstant_array_refs mark the source of an IFN_LOAD_LANES
call and the destination of an IFN_STORE_LANES call as addressable,
so that they don't end up being REG rtxes during expansion.
I had to move the discover_nonconstant_array_refs call outside the
currently_expanding_to_rtl block since otherwise mark_addressable
just queues the decision for later.
