[AArch64] Fix for gcc-7 regression PR 80530

This patch fixes the regression caused by the changes to add square root
estimation when compiling for xgene-1 or exynos-m1 targets.

The issue is that the expand path for the reciprocal estimate square
root pattern assumes that pattern cannot fail once it has been decided
that this expansion path is available, but because the logic deep inside
aarch64_emit_approx_sqrt() differs from use_rsqrt_p() the two disagree
as to what is safe.

different choices here.

Build body of subprogram that has a class-wide condition that
contains calls to other primitives.
(Build_Class_Wide_Clone_Call); Build a call to the common
class-wide clone of a subprogram with classwide conditions. The
body of the subprogram becomes a wrapper for a call to the
clone. The inherited operation becomes a similar wrapper to which
modified conditions apply, and the call to the clone includes
the proper conversion in a call the parent operation.
(Build_Class_Wide_Clone_Decl (Spec_Id : Entity_Id): For a
subprogram that has a classwide condition that contains calls to
other primitives, build an internal subprogram that is invoked
through a type-specific wrapper for all inherited subprograms
that may have a modified condition.
* sem_prag.adb (Check_References): If subprogram has a classwide
condition, create entity for corresponding clone, to be invoked
through wrapper subprograns.
(Analyze_Pre_Post_Condition_In_Decl_Part): Do not emit error
message about placement if pragma isi internally generated.
* sem_ch6.adb (Analyze_Subprogram_Body_Helper): If subprogram has
a classwide clone, build body of clone as copy of original body,
and rewrite original body as a wrapper as a wrapper for a call to
the clone, so that it incorporates the original pre/postconditions
of the subprogram.
* freeze.adb (Check_Inherited_Conditions): For an inherited
subprogram that inherits a classwide condition, build spec and
body of corresponding wrapper so that call to inherited operation
gets the modified conditions.
* contracts.adb (Analyze_Contracts): If analysis of classwide
condition has created a clone for a primitive operation, analyze
declaration of clone.

Add dg-line

Context: there are currently two types of line number supported in

absolute line number, it's immediately clear what line number is meant, but
when a line is added at the start of the file, the line number needs to be

line numbers become large, it becomes less clear what line it refers to, and
when adding a line inbetween the directive using the relative line number and
the line it refers to, the relative line number still needs to be updated.
