Avoid ARB in simpleSexp grammar and parser


# 3f96182e 06-Mar-2017 Ramana Kumar <ramana@member.fsf.org>

Fix simpleSexpPEG

Fallout from 099a4487eaa2f9c1f635616d600ed460e249bb58


# 5f72e477 10-Feb-2017 H.Feree <h.feree@kent.ac.uk>

Cleaner approach of location in parser


# a2116435 25-Sep-2015 Michael Norrish <Michael.Norrish@nicta.com.au>

Improve sexp parsing to handle dotted lists better

Also move some peg_eval theorems from CakeML to pegTheory and use these
to simplify proof about valid symbols.


# fa568621 24-Sep-2015 Ramana Kumar <ramana@member.fsf.org>

define valid_sexp

the only restriction is on symbols (hopefully that's enough for parsing
back what's printed)


# d126ddb9 24-Sep-2015 Ramana Kumar <ramana@member.fsf.org>

save fdom and applieds, and clean saved theorem names in simpleSexpPEG


# e8b1de20 24-Sep-2015 Ramana Kumar <ramana@member.fsf.org>

fix sexpPEG so it is wfG (and still passes tests)

rather ugly peg expression for sexpnum, but seems hard to avoid


# d017fb2f 23-Sep-2015 Ramana Kumar <ramana@member.fsf.org>

prove sexpPEG is NOT well-formed
