Carp: Avoid run-time mods; StrVal workarounds
Carp needs to avoid loading modules while reporting errors, because
it may be invoked via $SIG{__DIE__} after a syntax error, when BEGIN
blocks are forbidden.
Before this commit (as of v5.27.8-360-gc99363a) it was doing just that
for reference arguments within stack traces.
That means we either need to load overload.pm at start-up so that
overload::StrVal is already available, or avoid overload::StrVal
altogether.
It turns out that various versions of overload::StrVal have
their own problems that prevent Carp from using them (out-
lined in the comments added to Carp.pm and also described at
<https://rt.perl.org/Ticket/Display.html?id=132902#txn-1535564>).
So we now follow two approaches: If overloading.pm is available, use
that; otherwise, use a hideous workaround inspired by ancient imple-
entations of overload::StrVal and Scalar::Util::blessed, while avoid-
ing the bugs in those old versions.
