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
passes for test*iseqsig

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.

Ville pointed out that our paren init of aggregates doesn't work for
auto a = new A(1, 2, 3);
and I think it should:
A new-expression that creates an object of type T initializes that object
as follows:
...
-- Otherwise, the new-initializer is interpreted according to the
initialization rules of [dcl.init] for direct-initialization.
so I think it follows that we should perform dcl.init#17.6.2.2.
