Refactor helper function for feature + warnings in op.c
New helper functions to avoid some copy-paste. Also because I'm
otherwise about to add a third copy.

Log Message:
-----------
Rename perly.y's "list_of_scalars" to "list_of_itervars"
Currently these are all scalar variables, but soon I will add the
ability for iteration variables to be refaliases, so they won't
necessarily all be scalars any more.

Log Message:

More efficient `foreach \my $VAR` implementation
* Define a new private op constant OPpITER_REFALIAS
* Presence of this flag on OP_ITER means the iteration var is a
refalias
* Throw away the LVREF/REFGEN part of the optree in favour of just
setting this flag
This change is useful on its own, and also a good stepping-stone towards
being able to implement multiple refalias variables in foreach; as per
https://github.com/Perl/perl5/issues/24027

Log Message:
-----------
Allow multivariable foreach to use refaliases
As noted by https://github.com/Perl/perl5/issues/24027, while multivar
foreach and refalias foreach have each been available separately for
some time now, it wasn't possible to combine the two until now.
This current implementation does have limits on the number of variables
in total are allowed in a multivariable foreach loop if any are
refaliases (no more than 256), and which ones can be refaliases (none
past the 24th) that are all to do with the way I am abusing the U32
`op_targ` field to store the variable count in the lower 8 bits, and a
bitmask of which vars are refaliases in the upper 24 bits. I decided to
do that as it means I don't have to make the `OP_ITER` op any larger -
such as by expanding it to an UNOP_AUX to give it that extra storage
space. In practice I don't imagine those limits will be a problem for
any practical use-case.
If in a future version we did want to expand on those limits, I think it
would be possible by moving the `refalias_mask` storage to a PV stored
in the UNOP_AUX vector, or somesuch.
