This adds an assert to enforce_access to verify that we don't defer
access checks of dependent decls -- we should instead be rechecking the
access of such a decl after tsubst'ing into the user of the decl.
gcc/cp/ChangeLog:
* pt.c (perform_instantiation_time_access_checks): No need to
tsubst into decl.
* semantics.c (enforce_access): Verify that decl is not
dependent.
The previous patch mostly avoided making any changes that had no
functional impact, such as adjusting now-outdated comments and
performing renamings. Such changes have been consolidated to this
followup patch for easier review.
The main change here is that we now reuse struct deferred_access_check
as the element type of the vector TI_TYPEDEFS_NEEDING_ACCESS_CHECKING
(now renamed to TI_DEFERRED_ACCESS_CHECKS, since it may contain any kind
of access check).

This patch generalizes our existing functionality for deferring access
checking of typedefs when parsing a function or class template to now
defer all kinds of access checks until template instantiation time,
including member function and member object accesses.
Since all access checks eventually go through enforce_access, the main
component of this patch is new handling inside enforce_access to defer
the current access check if we're inside a template. The bulk of the
rest of the patch consists of removing now-unneeded code pertaining to
suppressing access checks inside templates or pertaining to
typedef-specific access handling. Renamings and other changes with no
functional impact have been split off into the followup patch.

The following avoids calling set_mem_attributes on the
DECL_INITIAL of a CONST_DECL which seems pointless since there
cannot be a sensible MEM_EXPR derived from that. We're overwriting
both other possibly useful info, alias-set and alignment immediately
so the following patch simply removes the call instead of making
the function deal with even more (unexpected) trees that are not
memory accesses.

* Make-lang.in: Always define version, minor and release

gimplify_modify_expr_rhs has an optimization whereby the assignment to
an aggregate variable from a read-only object with a DECL_INITIAL is
optimized into the direct assignment of the DECL_INITIAL, provided that
no temporary is created in the process.
The optimization is blocked if the read-only object is volatile, which
is OK as per the semantics of volatile, but also if the target variable
is volatile, on the grounds that the modified assignment might end up
being done on a per field basis, which is also OK. But this latter
restriction is enforced a priori and there are cases where the modified
assignment would be OK, for example if there is only one field or the
DECL_INITIAL is equivalent to the empty CONSTRUCTOR, i.e. all zeros.
So, in the latter case, the patch changes gimplify_modify_expr_rhs to ask
gimplify_init_constructor whether the assignment would be done as a block,
which is easy because gimplify_init_constructor knows that it must create
a temporary if the LHS is volatile and this would not be the case, so it's
just a matter of completing the NOTIFY_TEMP_CREATION mechanism.
gcc/ChangeLog
* gimplify.c (gimplify_init_constructor) <AGGREGATE_TYPE>: Declare
new ENSURE_SINGLE_ACCESS constant and move variables down. If it is
true and all elements are zero, then always clear. Return GS_ERROR

the type is aggregate non-addressable, ask gimplify_init_constructor
whether it can generate a single access to the target.

This fixes an issue with reverse storage order in SRA, which is caught
by the built-in verifier in verify_sra_access_forest. The problem is
that propagate_subaccesses_from_rhs changes the type of an access
from aggregate to scalar and, as discussed elsewhere, this must be
done with extra care in the presence of reverse storage order.

since Alexandre's revamp of dump files handling in
r11-627-g1dedc12d186, BRIG FE has been receiving slightly different
-dumpbase (e.g. smoke_test.brig instead of smoke_test.hsail.brig when
compiling file smoke_test.hsail.brig) and the testsuite then could not
find the generated dump files it wanted to scan. I have not really
