cvc4 errors in local test

[cblp]

Interesting, Travis reports everything is OK, but when I locally run make test or make travis-test I have following 5 errors:

1. should be safe

   1. foo9

      CVC4 Error:
          Parse Error: /tmp/cvc4-inputs/cvc4input18130801541579068977.cvc:43.40: Unexpected token: '['.

      Haskell code:

      ; bFoo :: (Array 4 Uint8)
      }
      |]
      
      ...
      store (f ~> bFoo ! 0) 1
      ...

      CVC4 code:

      ...

   2. foo18

Why it can be?

$ cvc4 --version
This is CVC4 version 1.3
compiled with GCC version 4.7.2

There are at least two problems right now: (1) there is a known parsing bug in CVC4; that is why Travis pulls down a particular build, and (2) there are some known issues with the symbolic simulator, in general.

I think the thing to do until @eddywestbrook gets a chance to integrate the new symbolic simulator is for me to deprecate the CVC4 for checks in Travis-CI.

Testing on https://github.com/GaloisInc/ivory/tree/deprecate/cvc4 ...

[cblp]

But why? CVC4 works good on Travis!

Oh, ok. We could keep running it on Travis, but as I mentioned, it should be replaced soon anyway.
