Title: Add support for FORMAT and LVALUE refs

This adds explicit display support for FORMAT and LVALUE refs. FORMAT refs are, as best as I can tell, opaque, so they're just displayed as "FORMAT". LVALUE refs shown as "LVALUE" followed by the normal scalar ref handling, eg:
my $foo = substr("abc",2);
p $foo;
Will result in:
LVALUE "c"
