We currently have a nasty error when trying to use the __crc* intrinsics
with an -mfloat-abi=hard.
That is because the target pragma guarding them uses armv8-a+crc that
does not include fp by default.
So we get errors like:
error: '-mfloat-abi=hard': selected processor lacks an FPU
This patch fixes that by using an FP-enabled arch target pragma to guard
these intrinsics when floating-point is available.
That way both the softfloat and hardfloat variants work.
* config/arm/arm_acle.h: Use arch=armv8-a+crc+simd pragma for CRC32
intrinsics if __ARM_FP.

Remove the remaining Neon adddi3, subdi3 and negdi2 patterns. As a result
adddi3, subdi3 and negdi2 can now always be expanded early irrespectively of
whether Neon is available. Also expand the extenddi patterns at the same
time. Several Neon arch attributes are no longer used and removed.
Code generation is improved in all cases, saving another 400-500 instructions
from the PR77308 testcase (total improvement is over 1700 instructions with
-mcpu=cortex-a57 -O2).

Like the logical operations, expand all shifts early rather than only
sometimes. The Neon shift expansions are never emitted (not even with
-fneon-for-64bits), so they are not useful. So all the late expansions
and Neon shift patterns can be removed, and shifts are more optimized
as a result. Since some extend patterns use Neon DImode shifts, remove
the Neon extend variants and related splits.
A simple example now generates the same efficient code after this
patch with -mfpu=neon and -mfpu=vfp (previously just the fact of
having Neon enabled resulted inefficient code for no reason).

Cleanup the logical DImode operations since the current implementation is way
too complicated. Thumb-1, Thumb-2, VFP/Neon and iwMMXt all work differently,
resulting in a bewildering number of expansions, patterns and splits across
several md files. All this complexity is counterproductive and results in
inefficient code.
A much simpler approach is to split these operations early in the expander
so that optimizations and register allocation are applied on the 32-bit halves.
Codegeneration is unchanged on Thumb-1 and Arm/Thumb-2 without Neon or iwMMXt
(which already expand these instructions early). With Neon these changes save
~1000 instructions from the PR77308 testcase, mostly by significantly reducing
register pressure and spilling.

In the case of a task declaring an entry with an aliased formal
parameter of a limited class-wide type, the front end was creating a
master object (_master) for the access type generated for such an entry
formal inside the task specification, even though such access types
don't need an associated master. The master object wasn't being copied
into the procedure expanded for the task body, but a renaming for the
master appeared in the statements of the task body, and the LLVM back
end rejects this since the master object doesn't appear in the expanded
task procedure (for some reason, gigi doesn't complain). This is fixed
by suppressing the creation of the master object in the case where the
access-to-limited-class-wide access type is the type of a component in
an entry's parameter block. This is similar to the suppression done for
the master object in other cases, where the access type designates a
type explicitly containing tasks (though the suppression involves
testing Comes_From_Source in that case).
No simple test (and this only affects the LLVM-based compiler).

* exp_ch3.adb (Build_Master): Suppress call to
Build_Class_Wide_Master in the case where the
access-to-limited-class-wide type was created for a component in
an entry's formal parameter
block (Is_Parameter_Block_Component_Type), to prevent a master
from being created for such access types generated by the front
end in a task spec for entry formals in a parameter block. Add
a ??? about whether this suppression should be done more
generally (such as by using Comes_From_Source).

This fixes a (sub)type mismatch in the expansion of an extended return
statement generated for a built-in-place function that doesn't need a
BIP_Alloc_Form parameter but returns unconstrained.
No functional changes.

* exp_ch6.adb (Expand_N_Extended_Return_Statement): In the case
of a built-in-place function that doesn't need a BIP_Alloc_Form
parameter but returns unconstrained, build the return
consistently using the function's result subtype. Remove bypass
added in previous change.

It was unusual for the analysis phase of compiler to rewrite static
expression of pragma Entry_Queue_Length with its value. This typically
happens when expanding the AST and only if needed for a given backend.
In particular, GNATprove doesn't need such an expansion and actually
needs the unrewritten AST to detect references to constants declared
with SPARK_Mode => Off within a code with SPARK_Mode => On.
This change has no impact on compilation, so no frontend test is
provided.

GNATprove directly handles non-null access checks, and requires that the
frontend does not insert explicit checks in the form of conditional
exceptions being raised. Now fixed.
There is no impact on compilation.

Ownership checking done as in GNATprove should ignore address of
subprograms, as it applies only on objects. Now fixed.

This fixes an assertion failure on the instantiation of a generic
package on a type derived from the private view of a protected type,
ultimately caused by Finalize_Address returning Empty for the subtype
built for the generic actual type of the instantiation.
Finalize_Address has a special processing for untagged derivations of
private views, but it would no longer trigger for the subtype because
this subtype is now represented as a subtype of an implicit derived base
type instead of as the derived type of an implicit subtype previously.

The compiler crashes processing an internally generated cloned tree that
