arm: Fix general issues with patterns for VLLDM and VLSTM
Both lazy_store_multiple_insn and lazy_load_multiple_insn contain
invalid RTL (eg they contain a post_inc statement outside of a mem).
What's more, the instructions concerned do not modify their input
address register. We probably got away with this because they are
generated so late in the compilation that no subsequent pass needed to
understand them. Nevertheless, this could cause problems someday, so
fixed to use a simple legal unspec.
gcc:
* config/arm/vfp.md (lazy_store_multiple_insn): Rewrite as valid RTL.
(lazy_load_multiple_insn): Likewise.
