compiler, runtime, reflect: generate hash functions only for map keys
Right now we generate hash functions for all types, just in case they
are used as map keys. That's a lot of wasted effort and binary size
for types which will never be used as a map key. Instead, generate
hash functions only for types that we know are map keys.
Just doing that is a bit too simple, since maps with an interface type
as a key might have to hash any concrete key type that implements that
interface. So for that case, implement hashing of such types at
runtime (instead of with generated code). It will be slower, but only
for maps with interface types as keys, and maybe only a bit slower as
the aeshash time probably dominates the dispatch time.
Reorg where we keep the equals and hash functions. Move the hash function
from the key type to the map type, saving a field in every non-map type.
That leaves only one function in the alg structure, so get rid of that and
just keep the equal function in the type descriptor itself.
While we're here, reorganize the rtype struct to more closely match
the gc version.

compiler: split writing of equal and hash functions for types
Separate the generation of type equality and hash functions, rather
than doing them in a single operation.
This is almost entirely a pure refactoring in preparation for
generating hash functions only for types that are map keys. The only
change in generated code is that for types that are the size of
numeric types, but not aligned like numeric types, such as [8]byte,
now use standard hash functions. They previously used special-purpose
hash functions because they required special-purpose equal functions.

Fix SSA update when vectorisation adds a vdef to a read-only loop
This patch fixes an awkward corner case in which:
(a) we apply if-conversion to a loop;
(b) the original scalar loop doesn't have a vdef, and thus doesn't
need a virtual phi;
(c) the vectorised main loop does need a vdef and a virtual phi (see below);
(d) we also vectorise the epilogue; and
(e) the vectorised epilogue still needs a scalar epilogue
The specific case in which (c) applies is if a read-only loop is
vectorised using IFN_LOAD_LANES, which uses clobber statements to
mark the lifetime of the temporary array.
The vectoriser relies on the SSA renamer to update virtual operands.
All would probably be well if it postponed this update until after
it had vectorised both the main loop and the epilogue loop. However,
when vectorising the epilogue, vect_do_peeling does:
create_lcssa_for_virtual_phi (loop);
update_ssa (TODO_update_ssa_only_virtuals);
(with "loop" in this case being the to-be-vectorised epilogue loop).
So the vectoriser puts the virtual operand into SSA form for the
vectorised main loop as a separate step, during the early stages
of vectorising the epilogue.
I wasn't sure at first why that update_ssa was there. It looked
initially like it was related to create_lcssa_for_virtual_phi,
which seemed strange when create_lcssa_for_virtual_phi keeps the
SSA form up-to-date. But before r241099 it had the following comment,
which AFAICT is still the reason:
/* We might have a queued need to update virtual SSA form. As we
delete the update SSA machinery below after doing a regular
incremental SSA update during loop copying make sure we don't
lose that fact.
??? Needing to update virtual SSA form by renaming is unfortunate
but not all of the vectorizer code inserting new loads / stores
properly assigns virtual operands to those statements. */
The patch restores that comment since IMO it's helpful.
(a), (d) and (e) mean that we copy the original un-if-converted scalar
loop to act as the scalar epilogue. The update_ssa above means that this
copying needs to cope with any new virtual SSA names in the main loop.
The code to do that (reasonably) assumed that one of two things was true:
(1) the scalar loop and the vector loops don't have vdefs, and so no
virtual operand update is needed. The definition that applies
on entry to the loops is the same in all cases.
(2) the scalar loop and the vector loops have virtual phis, and so --
after applying create_lcssa_for_virtual_phi on the to-be-vectorised
epilogue loop -- the virtual operand update can be handled in the
same way as for normal SSA names.
But (b) and (c) together mean that the scalar loop and the
still-to-be-vectorised epilogue loop have no virtual phi that (2)
can use. We'd therefore keep the original vuses when duplicating,
rather than updating them to the definition that applies on exit
from the epilogue loop. (Since the epilogue is still unvectorised
and has no vdefs, the definition that applies on exit is the same
as the one that applies on entry.)
This patch therefore adds a third case: the scalar loop and
to-be-vectorised epilogue have no virtual defs, but the main loop does.

Unshare DR_STEP before gimplifying it
In this testcase we use an unmasked SVE loop with an Advanced SIMD
epilogue (because we don't yet support fully-masked downward loops).
The main loop uses a gather load for the strided access while the
epilogue loop builds the access from scalars instead. In both cases
we gimplify expressions based on the DR_STEP and insert them in the
loop preheader.
The problem was that the gather load code didn't copy the DR_STEP before
gimplifying it, meaning that the epilogue loop tried to reuse a result
from the (non-dominating) main loop preheader.
It looks at first glance like there could be other instances of this too,
but this patch just deals with the gather/scatter case.
