ASTify ord, chr, length
ASTify lc and friends + quotemeta
pre/post inc/dec (have fun generating the code for these...)
undef($x) and undef
Compiler warning fix
Fix fall-through bug in switch statement that is too large

I know. It's getting messy.
Remotely similar thing to "perl -MO=Concise -e ... for ASTs
AST for //
Add missing binops to AST generation
AST: implement $$x and \$x
Avoid unnecessary work in LISTOP marco - also fix OBIWAN
Implement substr as a listop
Move list of non-ast-op jittable Perl OPs to opcodes file
Regenerate OP filter macro (sorted now)
Fix JITable OP logic. Valid root OP imples valid OP

Also, start adding OP_CHOP & OP_SCHOP
AST: chop($x) and chop($x,$y)
AST: chomp($x), chomp($x, $y)

Alas, the parameters to chomp are a total FAIL still. Lists/pushmark and
friends aren't there yet and it's not clear to me at this time how to
best do that.

$ perl author_tools/jit_ast_dump.pl -c -e 'chomp($x, $y)'
 Listop 'chomp' (
   'UnJITable subtree'
 )
