In January I've added patterns to optimize SImode -> DImode sign or zero
extension of __builtin_popcount, this patch does the same for
__builtin_c[lt]z. Like most other instructions, the [tl]zcntl instructions
clear the upper 32 bits of the destination register and as the instructions
only result in values 0 to 32 inclusive, both sign and zero extensions
behave the same.

The following patch avoids keeping the inherited MEM_ATTRS when
set_mem_attributes_minus_bitpos is called with a variable ARRAY_REF.
The inherited ones may not reflect the correct offset and neither
does the updated alias-set match the inherited MEM_EXPR. This all
ends up confusing path-based alias-analysis, causing wrong-code.
The fix is to stop not adopting a MEM_EXPR for certain kinds of
expressions and instead handle everything we can. There's still
the constant kind trees case which I'm too lazy to look into right
now. I did refrain from adding SSA_NAME there and instead avoided
calling set_mem_attributes_minus_bitpos when debug expression
expansion ended up expanding a SSA definition RHS which should
already have taken care of setting the appropriate MEM_ATTRS.

The code in constexpr for looking up the actual type of the object and then
getting the virtual function from there broke for both of these tests: for
16, it assumed incorrectly that the DECL_VINDEX would apply to the most
derived type's vtable; for 17, it failed to consider that during
construction the base subobject is treated as being of the base type.
Fixed by just doing constant evaluation of the expression that looks up the
function in the vtable. This means that a virtual call will involve loading
the vptr, so we will reject some calls through non-constexpr variables that
we previously accepted, but this seems appropriate to me. None of our
testcases were affected.

This started breaking in GCC 8 because of the fix for PR15272; after that
change, we (correctly) remember the lookup from template parsing time that
found Base::foo through the non-dependent MiddleB base, and so we overlook
the overrider in MiddleA. But given that, the devirtualization condition
from the fix for PR59031 is insufficient; we know that d has to be a
Derived, and we found Base::foo in Base, but forcing a non-virtual call
gets the wrong function.
Fixed by removing the PR59031 code that the PR67184 patch moved to
build_over_call, and instead looking up the overrider in BINFO_VIRTUALS.

Confusingly, "get_return_object ()" can do two things:
- Firstly it can provide the return object for the ramp function (as
the name suggests).
- Secondly if the type of the ramp function is different from that
of the get_return_object call, this is used as a single parameter
to a CTOR for the ramp's return type.
In the first case we can rely on finish_return_stmt () to do the
necessary processing for copy elision.
In the second case, we should have passed a prvalue to the CTOR as
per the standard comment, but I had omitted the rvalue () call. Fixed
thus.

The operands in RTL patterns of MVE vector scatter store intrinsics are wrongly grouped,
because of which few vector loads and stores instructions are wrongly getting optimized
out with -O2.
A new predicate "mve_scatter_memory" is defined in this patch, this predicate returns TRUE on
matching: (mem(reg)) for MVE scatter store intrinsics.
This patch fixes the issue by adding define_expand pattern with "mve_scatter_memory" predicate
and calls the corresponding define_insn by passing register_operand as first argument.
This register_operand is extracted from the operand with "mve_scatter_memory" predicate in
define_expand pattern.

Since it was added in C++11, std::copy_n and std::ranges::copy_n should
do nothing given a negative size, but for random access iterators we add
the size to the iterator, possibly resulting in undefined behaviour.
Also, C++20 clarified that std::copy_n requires the Size type to be
convertible to an integral type. We previously assumed that it could be
directly used in arithmetic expressions, without conversion to an
integral type.

* par-ch3.adb (P_Identifier_Declarations): Add parsing of object
renamings that have neither a subtype_mark nor an
access_definition. Issue an error if the version is earlier than
Ada_2020, and suggest using -gnatX.
* sem_ch8.adb (Analyze_Object_Renaming): Handle
object_renaming_declarations that don't have an explicit
subtype. Errors are issued when the name is inappropriate or
ambiguous, and otherwise the Etype of the renaming entity is set
from the Etype of the renamed object.
* sem_util.adb (Has_Null_Exclusion): Allow for the case of no
subtype given in an N_Object_Renaming_Declaration.
* sprint.adb (Sprint_Node_Actual): Handle printing of
N_Object_Renaming_Declarations that are specified without an
explicit subtype.
