Eventually left recursion will work fine, but this is prevents an infinite loop for now.

Remove memoization in 'compile' word in pegs
...
This creates issues when recompiling a an existing EBNF parser for reasons I've not yet tracked down. Disabling it slows things down but makes things work correctly till I investigate the issue.

Fix performance regression in pegs
...
delay parser is improved to use a memoized quotation so the
construction and compilation of the parser at runtime only
occurs once.
Changed compile so it would use equality rather than identity
for memoization purposes.

Rip out packrat stuff

It was broken since the transition to generating compiled quotations. As far as I know, no one was using packrat-parse anyway.
Rework in progress...
