With my recent commit, I added a test that is not passing on all targets.
My change was valid for targets that have a vector/scalar shift/rotate optabs
(optab that supports vector shifted by scalar).
Since it does not seem to be easy to find out which targets would support it,
I am limiting the test to the targets that I know pass.

* sem_type.adb (Find_Unique_Type): A call to the universal
access equality operator requires one operand to be a universal
access, and the other to be an access type. There is no
requirement, as previously implied by this routine, that
pool-specific access types were illegal in this context.

* sem_ch6.adb
(New_Overloaded_Entity.Check_Conforming_Paramters): Add new
Conformance_Type parameter. With the value of
Subtype_Conformant, the behavior of Check_Conforming_Parameters
is unchanged. The call in Matching_Entry_Or_Subprogram to
instead passes in Type_Conformant. This corresponds to the use
of "type conformant" in Ada RM 9.4(11.4/3).
(New_Overloaded_Entity.Has_Matching_Entry_Or_Subprogram): Add
new Normalized_First_Parameter_Type function to help in ignoring
the distinction between protected and access-to-protected first
parameters when checking prefixed-view profile matching. Replace
computations of the type of the first parameter with calls to
this function as appropriate.

performed the expansion that for example may introduce actions
that specify explicit dereferences and run-time checks.

(Reset_Scope): Add handling for N_Freeze_Entity nodes, calling
Reset_Scopes recursively on the Actions of such nodes. Also, for

PR 92846:
ARC gcc generates FDCMP instructions which raises Invalid operation for
signaling NaN only. This causes glibc iseqsig() primitives to fail (in
the current ongoing glibc port to ARC)
So break up the hard float compares into tw categories and for unordered
compares generate the FDCMPF instructions which raised exception for
either NaNs.
With this fix testsuite/gcc.dg/torture/pr52451.c passes for ARC.
Also no regressions for the glibc math testsuite, only 6 additional

This patch provides a way to clone a pretty_printer.
This is needed so that we can capture text in a label_text and make
layout decisions based on it, using the policy of global_dc's printer,
whilst within a call to diagnostic_show_locus. We can't print with
the pretty_printer itself within a call to diagnostic_show_locus since
it has partly-buffered content.
