We were incorrectly accepting the use of 'this' at parse time and then
crashing when we tried to instantiate it. It is invalid because 'this' is
not in scope until after the function-cv-quals. So let's hoist setting
current_class_ptr up from cp_parser_late_return_type_opt into
cp_parser_direct_declarator where it can work for noexcept as well.

This enhances store-order preserving store motion to handle the case
of non-invariant dependent stores in the sequence of unconditionally
executed stores on exit by re-issueing them as part of the sequence
of stores on the exit. This fixes the observed regression of
gcc.target/i386/pr64110.c which relies on store-motion of 'b'
for a loop like
for (int i = 0; i < j; ++i)
*b++ = x;
where for correctness we now no longer apply store-motion. With
the patch we emit the correct
tem = b;
for (int i = 0; i < j; ++i)
{
tem = tem + 1;
*tem = x;
}
b = tem;
*tem = x;
preserving the original order of stores. A testcase reflecting
the miscompilation done by earlier GCC is added as well.
This also fixes the reported ICE in PR95025 and adds checking code
to catch it earlier - the issue was not-supported refs propagation
leaving stray refs in the sequence.

Given the C code:
unsigned long long inv(unsigned a, unsigned b, unsigned c)
{
return a ? b : ~c;
}
Prior to this patch, AArch64 GCC at -O2 generates:
inv:
cmp w0, 0
mvn w2, w2
csel w0, w1, w2, ne
ret
and after applying the patch, we get:
inv:
cmp w0, 0
csinv w0, w1, w2, ne
ret
The new pattern also catches the optimization for the symmetric case where the
body of foo reads a ? ~b : c.
Similarly, with the following code:
unsigned long long neg(unsigned a, unsigned b, unsigned c)
{
return a ? b : -c;
}
GCC at -O2 previously gave:
neg:
cmp w0, 0
neg w2, w2
csel w0, w1, w2, ne
but now gives:
neg:
cmp w0, 0
csneg w0, w1, w2, ne
ret
with the corresponding code for the symmetric case as above.

gnu_entity_name accordingly. Explicitly set the parallel type
for GNAT encodings.
Call create_type_decl in the misaligned case before maybe_pad_type.
<E_Array_Type>: Do not use the name of the implementation type for
a packed array when not using GNAT encodings.
<E_Array_Subtype>: Move around setting flags. Use the result of the
call to associate_original_type_to_packed_array for gnu_entity_name.
<E_Record_Subtype>: Create XVS type and XVZ variable only if debug
info is requested for the type.
Call create_type_decl if a padded type was created for a type entity
(gnat_to_gnu_component_type): Use local variable and adjust calls to
maybe_pad_type.
(gnat_to_gnu_subprog_type): Adjust call to maybe_pad_type.
(gnat_to_gnu_field): Likewise.
(validate_size): Adjust to renaming of macro.
(set_rm_size): Likewise.
(associate_original_type_to_packed_array): Adjust return type and
return the name of the original type if GNAT encodings are not used
* gcc-interface/misc.c (gnat_get_debug_typ): Remove obsolete stuff.
(gnat_get_fixed_point_type_info): Remove const qualifiers for tree.
(gnat_get_array_descr_info): Likewise and set variables lazily.
Remove call to maybe_debug_type. Simplify a few computations.
(enumerate_modes): Remove const qualifier for tree.
* gcc-interface/utils.c (make_type_from_size): Adjust to renaming.
(maybe_pad_type): Remove IS_USER_TYPE parameter and adjust. Remove
specific code for implementation types for packed arrays.
(compute_deferred_decl_context): Remove const qualifier for tree.
(convert): Adjust call to maybe_pad_type.
(unchecked_convert): Likewise.
* gcc-interface/utils2.c (is_simple_additive_expressio): Likewise.
This can happen because we build an array type on the fly in case there
is an apparent type inconsistency in the construct.
* gcc-interface/utils2.c (build_binary_op) <ARRAY_RANGE_REF>: Use
build_nonshared_array_type to build the common type and declare it.
This was already the case in -gnatp mode.
* gcc-interface/misc.c (gnat_init_gcc_eh): Do not override the user
for -fnon-call-exceptions in default mode.
This prevents gigi from making a local copy of large aggregates.
* gcc-interface/trans.c (lvalue_required_p) <N_Selected_Component>:
Merge with N_Slice.
<N_Allocator>: Move to...
(lvalue_for_aggregate_p): ...here. New function.
(Identifier_to_gnu): For an identifier with aggregate type, also
call lvalue_for_aggregate_p if lvalue_required_p returned false
before substituting the identifier with the constant.
