[This includes the commits from #15 and needs to be rebased before it's merged.]

This adds:

foreach my $foo (@bar) {...}
foreach $foo (@bar) {...}
foreach (@bar) {...}

while ( EXPR ) {...}
until ( EXPR ) {...}

Postfix of these is provided by #15.

After this MR, I want to cleanup the while/until from being under a ConditionOp to be a KeywordOp.
