  -----------
  pp.c/pp_hot.c - prevent aliasing or localizing read only value in a restricted hash

This also teaches t/porting/diag.t to handle hv_notallowed() errors.
It does not currently include tests, that can come tomorrow.

$ ./perl -Ilib -Mexperimental=refaliasing,declared_refs -le'my %h=(k=>1); Internals::SvREADONLY(%h,1);
    Internals::SvREADONLY($h{k},1); my $v2=2; local \$h{k} = \$v2'
Attempt to alias readonly key "k" in restricted hash at -e line 1.
